That very well could be as well. Some of the joints were off. The guy i have working on it said most people dont use a XYZ of 0,0,0 and that messes up a lot.
Also, he found the weights are really poorly done, so, its making a lot of bending and warping on animations. Only the arms and shoulders. We are working on resolving this now. For my company, not so much for release to resolve others issues … since im paying for this to be done on top of paying for this asset lol
note:
head, chest, stomach, hips and all of the legs parts seem to work near perfect on every animation i have tested (kubald fighting, flying mage 2, cover pro, rifle pro, pistol pro, locomotion system 2)
