Okay, I'll look into it.
The hospital is indeed very performance heavy in the public build because of a lot of technical reasons that don't have anything to do with your rig. Hopefully it's better in the newest build.
I've got your point. Saves states are something I'm working on to improve, and I'm always trying to put ways around doors to ensure the player wouldn't be softlock. If you want to load an earlier save and you're in the same area,you're better off going back to main menu first, otherwise the old area might not get fully unloaded. This is also a technical point I'm aware of.
