natranr: so I have a saved game after some time of playing around, and when I went back in to load the game, the game crashed.
Thiev: Sometimes save screenshot gets corrupted. Go to your save folder and remove any image files (like .bmp or .tga, can't remember which one is used in NWN). Make a backup to be on a safe side.
That's in case turning off shiny water doesn't work.
I know this is somehow a necro post, but THANK YOU SO MUCH, Thiev and Tallima! <3
I wasn't able to load my Savegame because of some unnokwn bugs. So i searched the forums for a pretty long time and was near to give it up. I tried to delete the screenshots and portraits from the save files, but nothing would help me until i read your advice to try to turn off shiny water.... and voila - everythings working fine, at least for now. :'D
Anyway, thanks for helping me out, even 4 years after you posted it. Much love, xoxo
