I could not do the special assignment in Undermine. I had done more than the 3 worldquests required to unlock it, but it did not open up. Upon relogging all I got is the message: Special Assignment: Capstone 1 - Unlock failed.
However, after a small report in game and some replies with a GM, it suddenly is fixed for me and I can do the assignment. But my wife still has the problem, and we have done all the world quests to open it together. So either the GM fixed it, or something is really buggy. But since the GM said I should report it (because they can not forward issues to the debug team I guess?) here’s your report.
