That's been the case for me since last year and i just returned to the game after a lengthy break from it. I click to mute them and it just automatically un-mutes the moment they start using their mic again. Not sure if it's on my end or whether the voice server on Connery is fubared once again.
Thanks, devs! You're being very helpful! How many did you recently hire? Over 20 new devs?! Mhmm. Yes. I can clearly see that.
