So players on my server have told me that they can't eat books, paper, leather, or string as a moth. I've tested and I'm having the same issue. Flower stamens and the other food sources such as apples and carrots work fine.
The version we are using is grounded_origins-fabric-1.18.2-1.2.0, as it is a 1.18.2 Fabric server.
I attached a list with all the mods we have.
modlist.txt
It's probably something stupid that I'm not realizing, or a mod conflict, but I'm not sure.

I can eat them just fine in the dev environment. It's probably an incompatibility with another mod. Eating items is handled through Apugli, not my mod, so head to the Apugli issues page if you manage to find what mod causes this. I don't have much time to test things out myself beyond confirming that it's a compatibility issue between Apugli and another mod.

Okay! I'll leave a note there then! Thanks!
