Minecraft version 1.20.1, Fabric - 0.15.11
Dungeon Difficulty 2.2.1 (latest)
Lodestone 1.6.23.1 (latest)

When both mods are active, the game crashes with error code 1.

In any size pack including smaller ones, having both Lodestone and Dungeon Difficulty causes a crash stemming from Dungeon Difficulty. I reported this on Lodestone first and they informed me of the issue.

"This has nothing to do with Cardinal components api, the culprit is Dungeon Difficulty, using a @reDIrect in its ItemStackMixin. Make a Issue on their github and ask them to use MixinExtra's @WrapOperation or @ModifyReturnValue" Lodestone Issue
