I've been playing the most recent version of Mo Bends for 1.12.2 and have noticed almost immediately the animations don't mesh with the Danny Phantom Addon very well, as the suit maintains Vanilla animations causing my character to move out of or around the costume

The Images provided are the clearest examples but far from the only ones, as almost every movement causes this disconnect. I believe it's due to the costume not being an actual armor set but a visual effect added separately.
