I have noticed that in some quests, the doors close automatically very quickly. Particularly in Temple of Hoar quest. Half the party could move into a room, and the door closes in the face of the rest of the party, sometimes unrealistically "pinning" one or more characters between the door and the enemies. Perhaps the doors could be set to close on quest reset, or the time until it happens greatly increased. I know I am not alone in this feeling.

Oh yes, my poor strength-sapped paladin (all the way down to 3 of course) was trying to leave after completion and couldn't make it from one door to the next without it closing. It was actually pretty humorous.

You know remove disease removes all -stat affects? You must've used it on someone else and saved none for yourself. How altruistic!

the point is that I can see doors in other areas of the server closing automatically, llike in town, but most times when a door is opened in the underdark it should remain open indefinitely because if we are going through a tomb and killing everything in there, who is closing that door anyway?
