Another day, another bug, another problem that would not happen in the open release of the game! (and another occasion to bother @NxA_Noxie 
)
I was playing on execution, and checking the scoreboard once dead to report a player. Meanwhile, the match started another round and I found myself stuck in the scoreboard with no way to move the next round, nor even chat. I pressed the console key which opened the console, removed the scoreboard, but I was still stuck. I had to wait for someone to kill me and I finally could play the next round normally.
In the next round, I planted the bomb but it made no sound at all. I hardly believe it but in case there is any link.
Cheers
