Playing SS2 on PC and got a message that Vault 88 was being attacked. I fast traveled directly into the vault, took care of the raiders at the entrance inside the vault. When I tried to quick save, the "in progress" icon just stayed on for several minutes and wouldn't complete, I ending up having to restart the computer. Same thing happened when I fast traveled nearby Vault 88 and went in, meeting the raiders inside the cave entrance. Couldn't save, quick save, had to restart the computer. Anyone else see this or have a solution?
