I was about to begin watchers keep, having spoken to the knights and then teleported to the pocket plane from the top of the keep, next to the knights. I told the spirit thingy in the pocket plane to bring me Viconia, then once i had her sorted out with spells and items i went to go back thru the door, where it normally asks you if you want to go to saradush or back from whence you came or whatever. But after clicking on the door, instead of asking me where i want to go, it loads but then nothing happens, the menu doesnt come up, and the interface remains hidden, and the mouse and keys are non responsive, the characters just sorta crammed into the doorway looking around. Is this a bug? I hope not cos i don't have any earlier saves.
This has happened to me as well, usually a reload fixes the problem. If not you might try deleting all the files in your Cache Folder, that seems to be able ti fix some issues.
The game autosave everytime you click on the door, the dialogue should come up after the save is complete. Try reloading the autosave file and try again. If that doesn't work, use CLUAConsole:MoveToArea("AR3000") to get you back to Watcher's Keep.
