time delayed crash on save/save corruption after arefu?

[nando420]

Arefu has always been one of my earlier stops to get the repair bobblehead from king's house but sooner or later there comes a place where I crash on save or autosave and it seems to be random and in the past its been Big Town - "the area between big town, vault 106, vault 101 and jury street " - the disposal area where the agility bobblehead is - the area where the the 2 ghouls and 1st keller tape is near arefu and a powerstation - etc, its always random and the only thing i can do is start a new game, I have a game where i never went to arefu and went around exploring the map and ive been pretty much everywhere and no problems, thats why i think it has to do with arefu, mainly the explosion when encountering evan king, theres no way to tell until afterwards, like my newest game i saved before i went to arefu and then did some things and got to moonbeam cinema and tried to save before taking on the 2 mutants near there and crash! was gonna load my before arefu save but decided to try again an no problems so i thought it was a fluke and overwrote my b4 arefu save (stupid move) quicksaved went to sleep (not in game) started the game today and right where i saved last night i saved again (didnt do anything) and am having the crash on save issue. Thats why i think its arefu related even though i dont have any mods that affect it.
