Joe, do ya really think all several hundred copies of DF could crash at the same time?
I'd heard 'bout yo' powerful auroras causin' disrupshuns, but, damn that a big ol' co-inky-dink. Mebbe this's one of those cases where the error is 'tween the keyboard and chair.
Clone, anything in y'all's error.log? Done the service uninstall/re-install cycle? Ya gots buffered gens?
