I figured I'd open a new thread for these issues (originally reported here), seeing as they are separate from the issue described in the thread where I had posted them.
The main issue is that Hiravias's head is detached from his body (offset issue.) Additionally, some characters have a different color for their complexion depending on whether it is their face or their body.
