I could be wrong, but during a "discussion" between 3? or more people caused me to mute them, and I was continually able to hear them about 7-9 seconds after I muted them, when I asked who was unmuting them, Cogburn started laughing, so I assumed he was doing this somehow, I could be wrong, if so, apologies, but damn me when my player list mute option suddenly decides to stop working.
