This is in the modpack Medieval MC Fabric, v19.5, which as far as I know is really the only major place these mods currently coexist.

Attached is an example affected item - The stats both do not display and do not apply - this chestplate should give +2 strength but does not.

I can not seem to find a scenario where affixes do work. Some players of the modpack have reported that they were able to get a working affix, though I can not verify this.

RelicEx items looted via DungeonDifficulty do work, however. I assume this is the fix you implemented in 3.3.1, but the smithing table upgrade does not apply this new NBT format. Updated the title for accuracy.

Hi there,
I appreciate the detailed report - I'll look into it.
Thanks.

I'm playing the same modpack, will add that the relicex relics also cannot be affixed to any gear from the Spellblades and Such (Formerly Spellblade Next) mod. Cannot affix relics to crafted, Tieredz affected, and Dungeon Difficulty affected loot for this specific mod.

@SideralisMusic Tieredz interaction should be okay, no?

I think this just means all Spellblade Next armor.

It may be something for that dev to change their attribute implementation, I remember they applied some workaround to have their stats work pre-relicex3.3.0 as it was experiencing the same stat erasure as Wizards.

Just an update, all other mods mentioned here have fixed their issues but the Dungeon Difficulty attribute modifiers incompatibility remains.
