Graphic and Character issues

Okay so this is a big problem that is really annoying. so when I open up spore and create a new save and start I just, play the game as normal. But then when after I mate to get a new part on my creature after I'm done my creature looks glitchy. I don't know how to explain it really, it just looks like his skin is corrupted or something. This also happens when I play with a already saved game, that creature gets the same problem. I haven't seen anyone else have this problem so if someone could help that would be great!
