Title says it.
(Note: This is on Steam!)
Ever since some time, the crosshairs are messed up. Don't tell me to play without them, even though I have. I want it back at the center! As you can see, the crosshair is not lined up to the red lines. Also, don't tell me to aim more to the right and up, as the crosshair actually moves by itself. You can't see it in the screenie, but it does. I've tried to replace the HUD files, tried to replace the chair sprites and hud stuff, and even tried removing them to revert to the original, but they still act the same way...
Just how would I fix this stupid problem?
