Not OP but my group has noticed this bug completely disappeared, THANK YOU.
Curiously since "lobby glitch" was fixed, we are now noticing a 6 player lobby glitch where we will lose 1 or half the lobby when searching for games as a 6 stack in MP. Never occurs with 1-5 player lobby, only a full 6. Happens with a mixed lobby of PC/Xbox and also with all 3 PC/Xbox/PSN. Our temporarily solution has been to cap lobbies at 5 players.
