"Deserted" map boss arena bug in multiplayer.

In the "Deserted" map, if one person starts the Boss fight before everyone is in the arena the arena entrance is non-interactable.

If the person in the boss arena then dies, the boss is inaccessible forever.

Also, if you walk past the boss arena checkpoint, and then die to a mob/monster, it wipes the whole area... A really bad decision on GGG's end. I don't know what they were trying to prove with changing boss fights. It is almost like they do not want people playing the game...
