I didn't want to post a new topic for this problem I have, so everything can be found back in one place.
But the problem I have is a bit different. I did the same as the people who posted before me, didn't burn Mpanza's cart that is. But I got back to Anthabert before going to the guard, and the dialogue I had with him pissed him off. I didn't want to kill him because I wanted the wine and I wanted to turn him in. So I ran out of his room and closed his door. The problem here is that the door got locked. And even after I go tell the guard the door remains locked. So I can't get to the bottle of wine ...
Does anyone have a solution for this? Thank you in advance ...
