In the Official Campaign, characters I think should be friendly suddenly go hostile! Whats wrong?
There have been a number of threads on various forums on this issue. The usual workaround in these cases is to go back to a previous saved game (rotating between a few saved games is probably a good idea in general anyway). 4.15: In the Hordes of the Underdark Official Campaign, the game always crashes just before the battle with the Valsharess. Help! This was fixed in version 1.66. Make sure you are using the latest version of Neverwinter Nights.
