The map is still preety much broken (cleaning everything just straight up removes earth, you can only select it once when launching the game)

Anyways here is how to fix the map

1. Go to SteamLibrary\steamapps\workshop\content\1118200\2522064424
   (SteamLibrary should be located in C:\Program Files\Steam by default)
   
   
2. Open up "main.cs" in notepad or any other text editor and remove
   using Ceras;
   at the 6'th line
   
   
3. After that save the file and you should be done yeayyea!11
   
   
4. Enable/Recompile the mod, reopen the game and before all the mods/contraptions load enter the play screen and wait, the map should appear when it all loads in

The mod is regarded as suspicious because it checks if you have fancy mode enabled, so you shouldn't worry abt that

Also as the creator said enable fog, set gravity to 0 and disable floodlights
