Sacrament Sewer Soft Lock

After grabbing the water channel key from the chest, I went straight back to sacrament via fast travel to repair weapons and armor. After repairing and selling some things I fast traveled back to sacrament sewer checkpoint but the key de-spawned from my inventory and now I can not open the water channel door. The chest is still there but it is open and empty. I can no longer interact with it. I’m not sure if the key actually de-spawned from my inventory or if it never entered my inventory in the first place.

did you by any chance use an exploit to get to the area boss before picking up the key? if so, that is a known issue.

but please don’t ask me how the exploit/glitch works :smiley:
