AI Summary: The game crashes when quitting loaded single-player games because the `multiplayer` status in `GameConfig` is stored as a string ("DISABLED") instead of its corresponding enum value. This causes issues when other parts of the code expect the enum's custom `__bool__` method. The proposed solution is to add a line to `migrate_game_config` to explicitly convert the string to the `MultiplayerStatus` enum during save migration, with an additional suggestion to also map `Faction` strings.
