The Server always crashes when trying to spawn a Zenith boss when I have "Curse Boss Items" set to true in the adventure.cfg

java.lang.ClassCastException: class net.minecraft.class_1900 cannot be cast to class io.github.fabricators_of_create.porting_lib.enchant.CustomEnchantingTableBehaviorEnchantment (net.minecraft.class_1900 and io.github.fabricators_of_create.porting_lib.enchant.CustomEnchantingTableBehaviorEnchantment are in unnamed module of loader net.fabricmc.loader.impl.launch.knot.KnotClassLoader @4f9a3314)
at dev.shadowsoffire.apotheosis.adventure.boss.ApothBoss.lambda$modifyBossItem$19(ApothBoss.java:283)

At ApothBoss.java line 283, the code indeed tries to enchant the bosses item with a curse, so I know for sure that this is the issue.

full log file here (keep in mind that this is a large modpack):

I DID ALSO TEST THIS IN A FULLY ISOLATED ENVIRONMENT:

latest.log

When I try to spawn a zenith boss via command, the game doesn't crash, but instead, an error gets thrown (tooltip shows the error):

The game did later crash, cuz a boss tried to spawn normally...
