Map is not showing up in select map dropdown

Check the top left of the screen and the log file to see if the map had any error during loading. Also make sure the map is properly installed through Fluxloader, and that all its dependencies are met. If you don't see any errors, and need further help, you can join the discord and ask in the modding chat.

Game crashes upon launch / loading of a save

If the game crashes upon loading or launch it means the last selected (or currently selected) map is invalid. You can use the Fluxloader config menu to change the selected map before entering the game. The Fluxloader should automatically switch back to the default map if the last loaded one is removed (invalid), but you may have disabled this in the global Fluxloader config.

Background has visual glitches

This is likely the result of loading a save with a map other than the one it was created with. Try loading the save with the same map it was originally created with.
