As the title indicates, I had a little booboo on the mesh for Tank Your Time, which had the faces showing. (Thanks to my friend Mura for noticing!!) I accidently had the auto smooth clicked on in Milkshape. But by the time I figured this out my Milkshape expired.

So I have a full version of Milkshape now, and was able to fix the problem. I'm really sorry for the inconvenience guys! I hope you will download this copy so you can have this shirt in your game.
**I have left the file name the same. So it should completely write over the existing file!
