guild quest wont complete

[Ristlin]

Our guild quest "big city life" has 36/36 members completed, it has not autocompleted and has been "finished" for over 12 hours.
Any help in this would be appreciated.

This has been mentioned in several threads already, most recently here (I think)
I'm afraid the Guild leader will have to contact Support (http://www.thesettlersonline.com/en/help-and-support) and see if they can resolve your issue.
