so I've noticed some things when editing fixed rooms. first of all, SkyTemple always marks them when an asterisk (*) - as if there were unsaved changes in that room - once you stop editing the room, even if you didn't make any changes. regardless if you make changes, reloading the ROM (saving or not) causes these errors on startup
