This bug is pretty irritating when it happens and it was happening in BFA. Often happening with your healer for some reason this bug makes it so other players in your party appear in the entrance zone standing still in the zone-in-spot (meanwhile they are actually running around and able to play the game normally). The way around it is too simply fight in the entrance or communicate LoS. It is next to impossible if you have a returning player or new to the game player to win a game when it happens largely due to the confusion of the bug itself.
