Now, I'm not sure if this is really a bug, but I have noticed it quite a bit.

When a T3 wolver (and sometimes even T2 wolvers) digs underground they come back up with. . . I guess you would call it a "bulge" in the middle of them, kinda like they still are in a ball. Problem is they clearly aren't and at times it looks pretty disturbing. Now this bug isn't really affecting gameplay so its not a big deal, but I just would like you guys to know.
