I keep on getting bugs with the map, where a chunk of some large structure will be missing, like the living quarters in the aruora, the majority of the lava precursor base, or the wierd portally room in the island precursor base. If I enter the missing area, I'll often get stuck, requiring an alt+f4.

How do I fix these parts of the map without starting a new save file?
