There is a bug in my male commando avatar (don't know about the other characters).

The wire model of the lower arm is odd shaped. My guess is that the lower arm should follow the green line.
It seems not to matter which sleeves i wear, because it's looking weird for multiple sleeves.
I found it while playing on the ipad2, but i'm not aware if this is a device related bug.
