Learn it from us "old school" in computer/console RPG games: Save a lot and save often. I mean Manual Save not Autosave. You save manually before entering a room/building. Once you get inside, save again in a separate slot or 2 slots so you have a working save while in the room/building. You can remove them once you get back out.
