This the same problem some people were experiencing in BETA! Unplugging the controller doesn't do anything. Here's part of the issue from the "solved" thread:
Suddenly in the middle of the round, I was unable to shoot any weapon, I noticed after a while, that when I press to jump the weapon fires, also I noticed that I can't sprint.
Also the weapon fires randomly. I was using Recon class at the time this bug showed up.
This game is unplayable for me. Third straight day. Switching to games that work for now. You guys knew about this bug since the Beta and didn't think it would be a problem for consoles?
