PUT THIS AT VERY BOTTOM.esp <--- FO3 Edit patch for all mods.

 

Basically, I can play the game (somewhat) fine without a lot of crashes, every now and then, it happens, usually around 10-20 minutes of play. However, upon entering Operation: Anchorage (I haven't tried any other expansions yet) it will play fine, until I decide to save the game, either quick save, regular save or simply leaving the area into a new one and causing auto-save to trigger. It crashes no matter what. Is there a fix? Is my load order screwy? I'd appreciate any help.
