So, Im not actually sure if this is a bug or not... Sorry if it isn't :)
Basically, pretty much all Dalek mod clothing items don't work with Mo' Bends.
(example: Dalek Mod Headphones using Mo' Bends flight animation)
Mo' Bends is an essential mod in my gameplay and it's shame that it doesnt work with The Dalek Mod
They do mention on their Curse Forge page that a patch can be made pretty easily, but I have no idea how to program patches.
