I'm getting errors in the server console every now and then looking like this: 21.10 22:58:40 [Server] Server thread/ERROR [Apotheosis : Adventure/]: Failed to execute LootRule minecraft:iron_chestplate/rare/EFFECT/0.33!. They come in intervals but with different items failing each time.

Having the same issue here - 1.18.2-5.7.2

If you want logs, files, whatever...let me know, happy to help.

fixed in 5.7.3

still there.. with v6.0.0

6.0.0 is outdated.

Reopening the issue due to it occurring in my server as well.
Apotheosis version 7.0.5, MC 1.20.1

This happened in the End, all loot as a result rolled without any affixes, just vanilla enchants.

During server startup these messages also show up, but I haven't been able to figure out how to fix them.

• 1 to this. Version 7.0.5 on MC 1.20.1, forge 47.1.3

This is causing people to crash in my server when getting close to the Iron's spellbook spells items when dropped on the floor.
Any ideas?

It is the responsibility of the loot category owner to ensure there are ample affixes - iron's spells, in this case.
