Was playing, saved the game after completing the quest in vault 95. Went out for the night (did nothing on my pc) First thing this morning I attempt to load the save. Immediate crash to desktop. No error at all, game just crashes.

1. I have no mods installed.

2. easily meet sys requirements, game auto defaults to "ultra"

3. I've reset the game files

4. I had multiple saves within the vault. no matter which one I load I CTD immediately

5. loading any save that isn't within vault 95 loads just fine.

Remove all the save files related to Vault 95 in your saves folder. Load a save before you got to Vault 95.

Go to a town far away from Commonwealth, let's say go to your home and sleep for 31 days.

After that, make a new manual save - exit game and load that save. Then try to go to Vault 95 again.
