Specific to 1.20pre:

• Change: Forage vessels only drop one type of clay at a time now(blue or red).
• Bugfix: Spawn protection around trader structures wasn't being disabled.
• Bugfix: Leather backpacks weren't in the hoarder's bought items.

Look to 1.5.0 for the full list of changes.

Changes

• Hoarder trader buys linen instead of sewing kits, and their demand for linen is now double what it was for sewing kits.
• Stones vessel removed from hoarder trader's sold items.
• Panning sand/gravel now has a chance to drop obsidian (alternative to stones vessel).
• Removed rope from farming vessel, let me know if you have any ideas on items that would fit well with the current ones in this vessel.
• Forage vessels only drop one type of clay at a time now(blue or fire).

Bugfixes

• Crop growth buff was being applied on client side and server side, fixed to only apply once.
• Newly spawned traders were showing 0 hours til restock.
• Every single creature was dropping bones, regardless of whether they normally place carcasses.

In the previous versions, i've said that 1.19 versions work for 1.20pre too, but i didnt realize that spawn protection for traders wasn't being applied, and leather bags weren't in their bought items. So just keep those two in mind.

• Removed fireclay from Forage vessel of Hoarder trader

Please look at the previous devlog for 1.4.0 changes, that version also works for 1.20pre if you'd rather get fireclay from vessels instead of crafting.

Big update time!

Killing tons of hares for redmeat was getting excessive, so:

• Animals now drop their bones when decaying rather than placing carcasses
• Doubled the gears traders will buy redmeat for and increased the amount they'll buy at a time.

Crop changes:

• Exanded the growth speed boost from flax to all crops
• Reverted guuranteed extra seed drop from flax
• Being stuck with low-fertility soil is too harsh, so now, you can now craft medium fertility soil, check the recipe in the handbook, it uses crushed bones(the texture looks like bonemeal because i cant make a new texture). 

I also moved all the changes to treasure hunter's inventory to a custom trader:

• Added the Hoarder trader who now sells the 3 previously added seed vessels and will sell all new additions unless stated otherwise
• Created new Farming & Forage vessels based on the originals (You'll see an asterisk* indictating these custom vessels)
• Took the stones from the previous Forage vessel and created a new Stones vessel with the addition of halite, chalk, and obsidian(which is a better material for tools than flint)

Let me know if i need to rebalance the vessels in any way.

Added a command to convert a nearby trader to any desired type, incase you'd like to play with a vanilla trader: "/convert_trader", just put the name of the trader after it. Example: "/convert_trader clothing"

Previously i forced traders to restock daily but i wasn't able to get that to show in the trader gui, but now they show the amount of hours until their next restock! 🎉

For 1.20pre, if you'd rather get fire-clay via crafting and not from forage vessel, get the 1.4.1 release.

• Replaced fireclay with redclay in the vessel loot tables as you can craft fireclay using either clay.

(If you want to play on 1.20pre without this change, the previous version should still work.)

• Added three new vessels to encompass all crop seeds.
• Added them to the treasure trader's items, replacing the original seed vessel.

(These vessels weren't appearing in the trader or creative menus in the previous- now deleted, release)

• Traders now restock daily. I didnt notice but after their first restock, the restock days would revert to being randomly chosen from 1-7 days. Ignore the days to restock in the gui now, i made it so traders will restock 1 day after their last restock.
• Traders always spawn as treasure traders. Couldn't figure out how to do this before, but i got it to work now. I'm not sure but the way i did it might not work on servers, let me know if it crashes or doesn't convert the trader.
