This bug seems to be random, but still reporting it, as maybe someone else has noticed it as well.
After playing an extended time period, leaving a group, where you were group leader (not sure if happens when you are not leader as well), game is turning monitor off (disconnecting it) for a second. When monitor turns back on, you are only faced with black game screen and only way to quit game is to close it from task manager. This kind of thing didn´t happen before TU17 and seems to be another issue with latest title update.
As said, it is random and i haven´t noticed any pattern, as some days nothing happens, but during other days, playing for extended time (around 5 hours), same behavior occurs.
