Castle Vault Not Ending

[Banana Wyvern]

After killing the two priest enemies in the Iron Castle Vault,
- The remaining revenants did not despawn.
- The objective Vanishing Treasure did not complete, it's timer ongoing.
- The chests within the arena the priests are found couldn't opened.
- The barrier blocking the entrance was not been removed, trapping me in the arena.

I waited the remainder of the timer on Vanishing Treasure to see if failing it would at least remove the barrier, however though the objective was removed from my ui the barrier did not go away.

I managed to free myself from the arena by abusing the unstuck menu option and crouching through the hole in the wall the opposite side of the arena entrance.

HI. We're aware of this issue occuring if Galleon Slave has been triggered, but not killed. If you managed to brick the Vault event other way, please let me know.

I can't fully remember anymore, but I'm confident Galley Slave had already been defeated by this time, there were also no calamities occurring at the time the bug was encountered (though I don't recall if I had triggered and ended a calamity during the fight)

I never tried to reproduce the bug, but I was using the Rotten Fiend heavy spell at the time and it has been the only time I've had the bug occur throughout the many runs on the vault I've completed.

EDIT: I tried to reproduce the bug twice since I first made this comment. I tried seeing if the Rotten Fiend spell made a difference in two runs, during which the bug was not reproduced.
In the second attempt I also attempted to trigger but not activate the Galley Slave boss*. I then attempted the vault in this state however the Galley Slave become fully active while clearing the vault forcing me to leave to defeat them before entering the
war priest arena.

Whether or not the Galley Slave was alive or not I do remember for certain that the Galley Slaves health bar was not active at the time I encountered the bug in my original post.


*I noticed on one run that if you approach the Galley Slave an audio que will trigger near his arena, this partially activates the boss but does not bring up his health bar or cause him to aggro.
If the player leaves then returns to the arena later you can see the boss is partially active as it is no longer in its sitting position and is standing at the ready.
