So there's a "new" glitch with one of the gopnik skins:

This happens when you try to recolor the tracksuit of the guy on the right (the guy on the right is the default playermodel model, the one in the middle is the same model but coloured black) the hands are ok but his entire head is changed to the colour you chose. This doesn't happen to any other skins.

If you go to my profile and look at my featured screenshot I made years ago using these models you can see that the guy with the beard skin didn't have this glitch before.

I doubt this will get fixed seeing as this is a kind of an old mod and this is a somewhat minor glitch but still thought I could let the creator know.
