Update coming! Brave testers needed!

[Patrik]

Hmm, sorry, I have a bit of a hard time understanding some of that. But it seems as if you might have saved the map once with "update 2", and that would have removed the skybox from the map.

If you want to make sure, create a map with a skybox texture in the original editor and try opening it with the latest version and it should still be there. If not, then something is very wrong.
