I can stay logged into MMOGs like EQ II for days on end without ever being kicked if not in a gh/housing zone. In the past week of new play, I have been kicked at least 6 times.
The most recent server non-response caused the first Foundry mission I tried to bug out, having a door closed at the start (has to be a bug that a door is there closed when the door is open when you enter the first time) after restarting the mission twice.
I wasted 90 minutes on this mission that started at the beginning of the daily Foundry special. What a waste of time. I had to drop it.
