Bug/Issue Boss inside the ancient vault do not spawn

Everytime i get to the boss room in the ancient vault he do not spawn and i get stuck inside the room (the exit dont open and cant go back the special door), i tried closing the vault several times and the same thing keeps happening.
On a side note i was playing a moded race, havent tried a vanilla race, it is the first time i entered the ancient vault
