i somehow lost ch8.tga and my crosshair somehow started to rotate. with a little testing i figured out it was loading ch8 .pcx . ch8a.pcx , and ch8b.pcx in rapid succession which makes it look as if rotating.
to get the crosshair to work u must delete ch8.tga and place the added files in pball/pics . then when ingame type crosshair 8 in console . (be sure to backup files)
