Another quest bug. While sieging that elven capital, however it's called (lol), you know the one that I mean, the bug shown in this vid happened:
I had my archers selected, and I opened the chat window at the same time. The game winked and the "Choose from where you wanna siege" window appeared. After selecting a place for the campament (I chose the same place where I was from the beginning) the reinforcment counter appeared again, from 15 minutes. However nothing else changed. Note that I killed the enemy lord and won the battle beforehand.
And this was on the orc questline.
