This occurred with my asura elementalist durmond priory story. I was defeated by an apparent mob of orrian but i don’t know what killed me honestly. The just appeared suddenly and i died that fast. This has also occurred in the Light in the darkness. Anyways i died and hit restart at checkpoint and i started at the start but could not get back to the vaults because a barrier is in the way. I’d also like to say such bugs also occurred in the early asura story such as npcs not attacking enemies and having to fend off ten or so golems by myself. Regardless plz take a closer look at the asura durmond priory story arc it has plenty that needs fixing.
