So, my fallout has recently crashed a lot when I am in sanctuary, near the last house that codsworth kills bloatflys in and trying to cross the bridge. I have tried 3 things to fix this issue, but can't seem to nail the issue I have tried; Removing all mods and starting afresh file. reinstalling fallout completely Organising my load order with LOOT I did find a fix for this but it seems to be a little bit of an issue because I need to activate mods, I have found that when I add [Archive]bInvalidateOlderFiles=1sResourceDataDirsFinal= To my Fallout4Custom.ini file it causes the game to crash to desktop, I know it is this file because I ran the game with no mods and only this line of code changed and it still crashed, but as soon as I removed it the same save file did not crash in sanctuary at all. Any help would be appreciated greatly.
