I submitted a post about this last week, but to clarify the dungeon vespers host has a bug where in the maze before the first boss, your power reserves wont even show if you collect or deposit them, but it will also soft lock the WHOLE rest of the dungeon behind the yellow airlock door, preventing you from even being able to open and progress through the dungeon. Dying and respawning doesn't work either. I had one time where it worked fine but any attempts afterwards have made this dungeon not able to beat flawlessly. Only fix i have seen is to die at the door and it will respawn you on the other side. which isnt a good fix either. PLEASE FIX SOON.
