Elenai Dodge 2 Rolling doesn't work when IC2C is present. The configs & ui still "work" it is just the roll itself that is not functioning when both mods are present.

I tested this with only the following in the mod folder: ElenaiDodge2, Feathers, & IC2C.

I have looked at the code and I see nothing that would cause this...

Maybe ask the other dev if he could provide insight in what could be the issue.

I have no problem patching it on my side if I am the cause. But I don't know "what the problem is" in the code.
