[2021] Got Stuck on Federal Emergency Bunker

On Federal Emergency Bunker in the room where you have to put out the fires. I shot the pipe over the door you have to exit through before I cleared the room and the fire didn't go out. Once I cleared the room and put all the other fires out I tried again but the sprinkler was already broken. Ended up having to throw a grenade in the fire and jumped on it to kill myself and restart from the last check point. On the retry, shooting the pipe above the exit door after clearing all the enemies in the room worked.
