Im trying to replace the arms on a model (original model), however when compiling the arms horribly break:
Image fileImage file
However, there seem to be no problems with the reference. The hand´s bone´s name´s match with the original reference, there are no mesh errors so far, and there is no bone twiching error from MS3D. I already tried deleting the ref and re-rigging the whole thing and $keepallbones command.

EDIT: Added propper model link
Model link.
