For the final area in the Ritual mission, one of my fireteam members(we'll say member 2) spawned at the beginning of "the bridge" leading to the boss island. He wasn't able to run across as it was considered a "turn back" zone, and for the most part when he killed his character he kept respawning there. It was fixed when myself and the other fireteam member(member 3) was teleported to the "thread weaving" area. When myself and member 3 were there, member 2's ghost was stuck on the other side of the long bridge
