I really love the animations that this mod brings but curios seem to be incompatible at the moment and don't properly rest on the player with the newly rigged body! Also I was wondering if I could Use Epic Fight in the Modpack I am working on!

The server I play on uses Curios and it seems to work just fine, could it be another mod causing the issue?

Sure. you can.

The mod does from a technical standpoint work with curios but visually the curios for me atleast do not attach to the newly rigged body like armor does. Most curios don't have a visual representation so this wouldn't matter but for ones that do cosmetically change your character like say the whoopee cushion from the Artifacts mod don't attach to the players newly rigged model.
