During my work with CC2 I have seen a lot of odd effects, which are hard to reproduce.
After a new start of the CC2 they often are gone.
This dos look how a memory leak and/or an overwriting of variables.

So I have tested a bit the memory use
after loading of Charakter Creator 2 431.740K
load the child avatar with hoodi 571.988K
load the child avatar with skirt 565.292K
activating Appearance Editor 1500.116K
unload Appearance Editor 759.504K
loading again girl with hoodi 785.740K
And this seems to become more over the time.
After some loading of different characters, opening and closing of the appearance editor I have loaded again the girl with the hoodi.
Now the memory use is already 1.561.352K
