Doors are always a tricky proposition in video games. In some games, getting caught between a door and the wall could mean instant death, while in other games you'd be lucky if the doors open at all. In Warzone, one particular door in the Karst Salt Mine was bugged so that anyone who touched it immediately died. Armor and health levels didn't matter; one touch and it was off to the Gulag.
Now, it's fairly easy to avoid this bug--it is just a door, after all. It's not even in a high-traffic area. You have to go out of your way to first find this door and then even further out of your way to run into it deliberately, but doing so would result in your untimely demise.
At least it used to. Today's patch unfortunately fixed this hilarious bug, so now the Salt Mine door is back to being just a harmless and far less exciting door. Other big bugs squashed in the recent patch include a strange issue where players would lose control of their operator if they used a Red Door where another player had previously died inside, and an issue with the QBZ-83 Blueprints causing some games to crash.
Along with a quick fix to the murder door, today's patch also brought a quick nerf to the MG 82. Max damage has been reduced from 30 to 29 while range was cut by 20%. The headshot crit multiplier was also reduced from 30% to 20%, and both vertical and horizontal recoil was increased. RavenSoft basically admitted in the patch notes that the MG 82 arrived overpowered and it was necessary to tamp it down before it totally warped the Warzone meta.
The Nail Gun is also in RavenSoft's sights for a possible future nerf, with the dev team noting it's killing players "about a bullet faster than we would like."
