Just to let you know that somebody (thanks u/nobody103!) reported a big bug with the map editor in version 0.3.2.2 where you won't be able to change the sea level of a map because the slider it is incorrectly mapped to the world temperature instead. Since I have no way to make a quick fix for this right now I decided to rollback to the previous public version (0.3.2.1) which doesn't have this issue. The previous version is almost exactly the same except it doesn't have a UI scaling option. So people using very high resolutions might have issues using this older version.
I'll try to create a patch version of 0.3.2 at some point next month but I don't want to promise it since I'm already halfway into 0.3.3. Please let me know if you have issues with the currently available version (0.3.2.1) to prioritize a fix.
