As the title says. I don't know what mod conflicts with the new version. Here's the crash log.

First one that I see is Spice of Life Carrot, seems like that's one of the mods affected by the new Applecore. After that, I'd look at everything that adds food, mainly mods that focus on food or have alot in the mod.

Sorry, I'm a doofus, this happens with just AppleCore alone. Don't use 3.1.2. Will release a fix in a bit.

Fixed in 3.1.3 once it gets approved: https://minecraft.curseforge.com/projects/applecore/files
