Just took forever to do a simple xmas scenario. Slow load time, zone refresh/freeze every few seconds, then the perfect storm of:
Out of web memory notice, zone refresh, and toys processing in the house, and badabing! Complete and utter computer freeze. Could not even punt out with Task Manager, had to do a hard shutdown and reboot. Not to mention the browser refreshes I had to do in order to see progress on the quests.
Had to attempt 3 times to drop a simple PFB on one guildie, then again on another trying to time it just perfectly between the zone refresh/freezes. They were successful, though.
