This happened to me 2 days ago playing Keegan. In the middle of the match I suddenly was unable to melee, shoot or throw nades. 30 seconds later or so it was like nothing happened and everything worked again and I didn’t think of much it.
Well, the same thing happened again today in the middle of Venom Run. Fun times. After inevitably dying I quit out of the lobby and was greeted with an endless loop of the sounds that usually plays when you’re awarded XP at the end of matches.
Both times I were in the same lobby for around 10 matches of Escape. First time I wasn’t host, 2nd time was my lobby.
I don’t run into this issue often. Pausing and unpausing the game quickly(or just hitting that button twice even when you’re not host) seems to fix this.
