Today it seems they\'re testing the fog; there\'s much more than the other day.
I too crash when entering the tavern, and have low fps near it, imo it can be related with those blinking dark boxes. The other day, less foggy, when I trespassed those boxes, the fog dissapeared completely, so I guess there\'s some collision between them.
If you can manage to reach the plaza (by double unsticking or by being teleported by a GM) you\'ll enjoy the less laggy plaza I\'ve ever seen, since the fog sorrounds you so much, that the client almost has to render your own char only, and that, if not in 1st person mode

EDIT: Lordbug adds that those crashes happen whenever trying to load a new sector. There\'s clearly some incompatibility between foggy zones, and not foggy ones.
