The 2 bugs that have been plaguing my friends and I (PS4) have been:
1. Being unable to rotate the camera. You can still run around and use abilities as well as interact with the environment, but you are unable to rotate the view with the right thumbstick. So far the only fix I have found is closing out of DA:I and restarting.
2. Warrior Treasure Room 'Doors' not opening. The warrior does the kick animation, but the wall remains, and once the glitch happens the door is unable to be interacted with by any other warriors in the party. The only fix I have found is for the warrior who glitched out the door to quit and then rejoin the match.
