Yup. Had the same thing happen with my robot body... It had little tank treads that 'rolled' when I walked along in the sprite. I had to edit it 5 times to get them to accept it. Then, about 3 months after it was accepted, they cited 'copyright issues' on the body I had hand drawn myself, and deleted it on christmas day (Maybe this should go in the christmas memories thread XD ). I resubmitted and it was accepted, then they deleted it about 4-5 months later again, claiming that they no longer allowed feet that 'didn't move.'
At least it was right before Japan Nexus... so I got full refund in time to buy some snazzy lanterns and stuff. BUT, the point is...
They should decide on submission rules, give ample notice if they are to change them, and make all them noob FP's (yeah this title works) go through upload bootcamp so they at least have some understanding as to what the hell is up with gummy bodies downloaded from Graal Depot vs. people's own hard work.
