Botania version: R1.10-346
Forge version: forge-1.12.1-14.22.0.2469
Fresh install of only Botania, Baubles and Forge.

I noticed the in-game vanilla crafting guide (green book icon) has the wrong recipes for various things, showing the right ingredients in the wrong locations. The items I noticed are the pestle & mortar and terra blade. I then noticed the pestle & mortar recipe changed, to another wrong recipe. however I have no idea what caused them to change as rebooting the game and even using a different Minecraft profile appears to show the same results now.

I made a fresh install of forge with the bare minimum for Botania to make sure it wasn't another mod in my pack causing it. I have not found it happening to any vanilla items,

this is MinecraftForge/MinecraftForge#4088

also seems like it's fixed in newer forge

Now this is pretty weird. Any fancy stuff you did that could cause this @williewillus?

@ShySkream but does the actual recipe itself have the right shape?

just checked myself, the actual recipe is correct, and it also shows correctly in JEI. I suspect forge patches have introduced a bug, but not sure yet.
