Thanks for confirming!

These errors are addressed in the development build for the upcoming v1.0.10 release. I’m working through testing and checking a few other reported issues before releasing it.

I’m aiming to have it ready within the week, provided testing goes well.

Thanks again for sharing the logs—it’s appreciated!

Hi Jess those fixed were rolled in to releace v1.0.9 thanks for the bug report, good catch!

Could you please provide

• Your Vintage Story version
• Your Butchering version
• The compatibility-patch version
• The name and version of every installed FotSA pack
• Your complete mod list
• what exactly is not working, e.g ground placement, placing on hooks (wall or ceeling and type), skinning, drops, bleeding, curing time, butchering

Where you have them Client-Main, Client-Debug and if possible Server-Main and Server-Debug log files.

One I know those details and have any relvent log files I can do some bug hunting and see what the issue is.

1.22.6
butchering 1.14.3
fotsa patch 1.0.8

the problem is that I cant pick them up, in a backpack slot or otherwise
also looks like i cant uplode the log files, ill try again in a different reply

Update:

This is rather straight forward, you are running older versions of some of the FotSA animal packs, that are no longer supported by the compatability patch v1.0.8.

The packs listed below will need to be updated to the supported versions (seen above in the description table).

• FotSA-Casuariidae-v1.1.11
• FotSA-Sirenia v1.0.30
• FotSA-Spheniscidae v1.0.17

Once upgraded everything should start working properly for you.

if you run in to any further issues please let me know.
Thanks again!

Oriognal Post:

Hey Foxx, thanks for that info ill get back to you once i have done some testing and let you know whats going on.
it may help with file uploading if you mirror this over on the github issues area lined above, youll need a github account to submit a issue.

Thank you, your communication with us is always great. 

❤️

that would appear to suggest you have updated to 1.0.8 but are running an unsupported version of some of the mods.

The errors shown above under the following namespace are not coming from this compatibility mod:

fotsa-butchering-compat

However the following are and i can directly address those:

This is due to the most recent update of Fauna of the Stone Age: Viverridae Plus to v1.0.10, I am currently working on compatability for that right now.
Untill the next compat update is releaced please down grade to the previous releace of this pack.

Additionally:
As a general compatibility recommendation, I would suggest running only one FotSA/Butchering compatibility suite at a time.

Both compatibility suites patch some of the same upstream content, so running them together may result in overlapping patches or make it harder to determine which mod is responsible for a particular issue.

This is not a recommendation of one compatibility mod over the other, only that whichever one you choose should ideally be run on its own.

💗💓💓 Thank you!

Excellent as always, if it's any help the only ones showing up in the console are:

Elephantidae v1.0.19
Elephantidae v1.0.20

Appreciate the kinda words and feedback & debug info

v1.0.8 is releaced and now covers the current FotSA Packs again, including Elephantidae! at version v1.0.20

More than likely need patching. I am currently looking in to the updates and will releace a new updated patch shortly.

Please let me know what versions of the FotSA mods you are running, as well as the version of Butchering you are using, and I’ll be able to take a look into this for you.

Update:
Just a note here: I can see you are running my compatibility patch alongside another compatibility patch. Running both together can cause issues.

All of the Dinornithidae errors above are coming from the other compatibility patch. From the paths it is trying to use, it looks like that patch is not compatible with the version of Dinornithidae you currently have installed.

The two Spheniscidae errors are coming from my patch. I’ll be able to investigate those properly once you provide the modpack details and the exact versions you are running.

Thank you

Thank you and you are very welcome!

can you post up your
client-main.log
client-debug.log
server-main.log
server-debug.log

VS Version
as well as ur mod list inc mod versions for me

ill take a look in to this cheers.

Thanks for the feedback! I’m always open to suggestions and ideas. Please feel free to add a feature request to the GitHub Issues page detailing your patch idea.

thanks for letting me know ill take a look at this and see if i can replicate the issue and  then figure out whats causing that issue for you, would you mind listing any other mods that your running incase its a cross mod compatability issue, thanks.

I’m going to answer this plainly, because calling the mod a “wholesale rip-off” after only a brief look through the repository is a serious accusation, and it does not fairly represent how the mod was put together.

I was given a specific task: provide working compatibility between Butchering and the current FotSA packs, do it using as few additional mods as possible, and have it ready by a fixed deadline.

When I started looking into it, I found your mod, Pepe’s mod and the open pull request to merge the two. I was genuinely pleased when I found that PR because I thought it might solve the problem for me. I watched it for several days, but nothing happened with it. It was not merged, no combined version was released, and there was still no single mod I could actually download, install and test.

An open PR is not a finished release. I cannot put an open PR onto a live server, and I could not wait indefinitely in the hope that it might be dealt with before my deadline. When that deadline arrived, the PR was still sitting there and the only available option was to install both of your separate mods.

Even using both mods would not have fully dealt with the setup I was working on. Butchering had received several updates and had reached version 1.14.2. FotSA packs had also been updated, new content and variants had appeared, and Butchering itself was now handling more FotSA animals natively. This meant that some of the older compatibility patches were no longer needed, while other newer animals and problems were not covered.

That is why I acted and made my own compatibility mod. The work that was needed had not been completed or released by either of you, and I had a deadline to meet. I was not going to leave the server without working compatibility simply because an open PR existed which nobody had yet actioned.

I did not just take your two mods, throw their files together and upload the result under my own name.

I reviewed:

• Butchering 1.14.2.

• 20 current FotSA animal packs.

• Butchering’s own existing FotSA support.

• Your compatibility mod.

• Pepe’s compatibility mod.

• Several older compatibility projects from previous game versions.

That review resulted in compatibility sections for 17 FotSA packs. Three of the 20 packs I checked were already fully supported by Butchering itself, so my mod does not interfere with or duplicate that work. Where Butchering already handles something correctly, it is left alone.

The mod also does considerably more than simply place your mod and Pepe’s mod into one package. It includes:

• Support for semitamed Caninae variants that were previously missed.

• Fixes for all affected Caninae babies being impossible to skin.

• The missing Caninae baby workload and blood-type settings.

• A correction for the incomplete female Caninae carcass definition.

• Better dead and hanging carcass models for Caninae animals.

• Restored butchering support for vanilla red and Arctic foxes while Caninae is installed.

• Missing sound settings for the affected Felinae lynxes.

• The missing Viverridae Plus sound settings for Nandiniidae.

• Separate conditional patches for each FotSA pack, so people can install one pack, several packs or all supported packs without the missing ones causing errors or failed patches.

The mod was released for Butchering 1.14.2. Since then, I have also checked it against Butchering 1.14.3 and have been running that combination on a live multiplayer server without any compatibility problems found so far.

Yes, I used both your mod and Pepe’s mod as references. I have never denied or tried to hide that. Both of you are named and credited on the mod page and in the repository because your earlier work was useful during my research.

Using something as a reference is not the same as taking the whole mod and claiming it as my own.

These are JSON compatibility patches aimed at the same animals, the same file paths and the same Butchering system. If two patches are both adding the same required behaviour to the same animal, parts of those files are naturally going to look similar. The animal names, paths, behaviour names and required values are determined by Butchering, FotSA and Vintage Story. They cannot simply be renamed or invented for the sake of making the files look different.

Where an older patch was still correct, the same basic result may appear in my mod after I checked it against the current files. Where an older patch was no longer needed, it was removed. Where it was incomplete or no longer worked properly, it was corrected or replaced. Nothing was accepted blindly just because it appeared in one of the earlier compatibility mods.

The credits were not added as some attempt to cover up copying. They were added because I openly acknowledged the work that came before mine. If I had intended to steal your work and pretend it was entirely my own, openly naming and crediting both you and Pepe throughout the project would make very little sense.

If you believe there is a particular file or section that was directly copied in a way that goes beyond the shared names, paths and JSON structure required to patch the same thing, then please point to it specifically. I will compare it properly, explain why it is there and address any genuine issue that is found.

What I do not accept is a broad accusation that the entire mod is a wholesale rip-off based on a brief look through the repository—especially when the proposed merger had not been completed, neither existing mod provided the full current compatibility that was needed, and I had to do the work myself to produce something that was actually current, complete and available to use.
