>>2220849Sorry. I didn't elaborate more but I had to get to work.
So it's actually two things. One throws the error. The other prevents the model from loading in the editor.
It's an easy fix if you know how to use a hexeditor but it's much easier to just do what
>>2220714 said and just resave the model.
The pic is what you'd have to do in a hexeditor. The offsets are not accurate since they will be different from model to model.
