Alright. I've figured it out. You can not fire while pressing Ctrl. That's all it is. That's all it ever was. I thought it was only while aiming at other players, but it was because any time I aim at a player, I press Ctrl (which I have tasked to Zoom). You cannot fire your gun or lean for some reason, while pressing Ctrl in 62.

I started playing today, planning on recording the glitch. I tested and tested and tested with a friend and it appeared the glitch had gone away. After an hour I had even killed a few players. I figured all was fixed with the recent update and I kept playing.

I can now recreate this 100% of the time. Would you like me to make some videos?

No, I don't have a wireless mouse or keyboard. In fact I went out and bought a new mouse to see if that's the problem.

Hi Geez,
It appears to be happening with all guns, though some more than others. The pump-action shotguns seem really bad. Probably the worst, it nearly never fires at a player. The Blaze seems to be least affected though it still does it. So far I have had the problem with both pump-action shotguns, the double barrel shotgun, the scorpion, the magnum revolver and the blaze. I don't think I've tried to shoot anyone with anything else. I've had it happen on different servers and characters.
