--Versions--
Accessories: 1.0.0
Accessories Compat Layer: 7.4.0
Mana and Artifice: 3.1.0.5
Forge: 47.4.0

--Issue--
Mana and Artifice generates staffs in loot tables with randomly generated spells attached to them. Similarly to how enchanted books are generated randomly. When Accessories is installed instead of Curios the loot table fails to generate anytime it tries to add a spell staff to the chest/barrel/etc. if the loot doesn't try to generate a spell staff then the generation succeeds. The same is true if you datapack the loot table to not generate spell staffs.

This issue does not occur with Curios.
I tested using only the mods required for Accessories and MnA to function.

If I assume that this version is Minecraft 1.20.1, but support has been dropped due to not having the time to properly fix these issues at this time while balancing other stuff.
