I made a body from scratch and nothing was wrong with it. I then uploaded it, it was fine, got accepted then I realised a tiny mistake. The grabbing animations were one pixel to the right when they should be back in place. I fix it, then upload it again to find they decide that it "doesn't have moving arms or legs, please use a better body template." I am using the official body template and it all looks perfect to me, even when I tested it in game.
Attached below are the files I tried uploading. In spookster.png I have made the arms move a little bit more to see if they would accept it.
If anyone knows what's wrong with it, please tell me! Any help would be appreciated!
