During the stealth part of the tutorial the guard with tire iron does not return to his position after the explosion. This makes it impossible to get through the double doors.

Try using one of your discpiline to incapacitat him. I was playing tremere and had the same issue. But using trance (of the domination-discipline) incapacitated him long enough to get along.

However: i have a similar problem, at the room where you need to use one of your discipline the first time. (after the sneaking-kill) The door is locked and I'm not able to unlock it. (no oprion for using the lockpick, even with bloodbuff, the locked lock-icon apears, however.)

On the other side: does the bug occure *every* time? Because, if you are detected, you will get another chance, automatically.
