The Great Vault Mission broke!

Can’t believe the mission won’t progress. It’s stuck at “open sanctum door” as there’s a check on it as I completed it, but the mission won’t update its objective. Anyone know of a fix, or do I have to start a new character…

Yo I got the exact same glitch, did u figure out how to fix it?

I am going through the same thing, restarted my game and console several times but im still stuck on the open sanctum and its really frustrating

I fixed it by going through the area again and making sure I go to the console where it would hit the button to trigger the event. It’s in the big courtyard before the final area on the second floor.

I can vouch for that, i fixed it by completely clearing out the room and it fixed itself, took a couple tries for me but it’s fixed
