That's news to me!
Are you playing with them as well on 1.22?
I saw this in the comments on Felinae:
"I killed a lynx, and attempted to look up in the guidebook how to turn its pelt into leather. Upon opening the guidebook page, the game crashed. It's consistant, does it every time. I guess this doesn't quite work in 1.22.2 yet!"
Are you getting this problem as well?
Hopefully this mod bypasses that by opting it into the butchering production line.

Anyway, thanks for the heads-up! I have the courage to try them out now for my new world ❤️

Edit:
Looking at some of the other FotSA mods, I've found other comments as well, such as:
"Just noticed you get crash to desktop if you attempt to look at the recipie for moose hide to huge hide. I believe the hides are using the old ID's pre 1.22 versus the new huge hides. Along with the fact you need raw fat and not rendered fat to turn them into pelts."
And a reply to that:
"was about to say this as well just had it happen
edit: To add on to this you cant even look at recipes pertaining to the huge hide it just crashes the game to desktop"
On the Capreolinae (big deer) mod.

I use Felinae Pantherinae-v1.2.13 and Capreolinae-v2.0.12 which are up to date currently. I have not had issues with crashes caused by either mod and they work as expected with Butchering on 1.22.2 for me. 

I added Elephantidae and Bovinae last night as someone in the comments of one of those said they were able to play fine with most of the FotSA mods on 1.22 and those are the last 2 I really care about and have been waiting on, but I don't think they play nice with my current modset. I got into the game fine for a bit, but then started crashing a bunch, something to do with a forge rendering a work item causing me to crash. Doesn't sound like it should be those mods, I did update a bunch last night, but to be safe for now, I have rolled back my server, and I am going to hold off on re-adding Elephantidae and Bovinae until they are properly marked for 1.22
