Hadnt had a crash till i got to nipton, tried to enter the town hall and would always crash - even reset the graphic settings no dice

then i went back and wanted to go to vicky vence casino again - same thing happend, im now crashing there too

tried to load a save game which i had while i was in vence casino -> instant crash

do save games share some kind of meta data ? it seems odd that what once worked now longer works, maybe i bugged some quest script/var - but there is no error log

wow i fixed it, i read about crashes in fallout 3 - and somebody said that he could sometimes fix crashes in buildings when using autotravel to another place / save / reload

this kind of worked for me, i loaded up a save game before i first went into vicky vence - it worked - then i loaded my save game where i stand before vicky vence and entered the building - it worked - previously i would always crash on that save
then, i auto traveld to nipton again and could enter the town hall this time too - so its some kind related to autotravel/save/reload
