Yeah, I know of the problem, thought that the site didnt have it any longer.

Oh, and regarding the mass, it thins out over a bigger volume, which means a lesser density directly afterwards. and the change back is the problem as it causes huge amounts of tissue to be useless, some parts would be able to logically ease back, but it would require a skeletal structure enabling it. Other tissue would basically fall of, like a felling of the old skin. messy indeed.

Oh and I guess I misunderstood as I was focused on a change in appearance and not just in stance ^^
