So I had quit out of the game before entering the Monolith on the ''Fury's Ascent'' quest on act 3 and it bugs out the door or what you call it so you can't move forward.
which is kinda game breaking as it makes you unable to continue the champaign. I have tried quitting, going in and out of the area and so on and nothing seems to work.
So don't quit at that moment and go through the door first so you don't get stuck.
To clarify, I talked with Valeria and Heimlock before i quit.
