It seems to happen only with a cursed soul, the crafty hair, and robot skin. It runs all the way to the point. I have not tested it with other classes or other maps. I don't foresee it becoming an issue, but I figured I should say something. I've been referring to it as my penis.
This is a known issue with certain items and the robot skins, particularly the scout and spy. Moreso with halloween-event items now there are zombie skins. If it becomes an issue (I don't think it will be given the halloween items will be unusable after a few more days) then we will look at options.
This happened to me once when I was playing a scout in Doublefort. I don't believe I was using any of the three things listed as causing the issue. I logged out and came back and it was still there. The only thing that seemed to cure it was a map change. But aside from being amusing and giving away my position like a GPS it didn't seem to disrupt the game much.
