With this update it looks like Space Engineers is taking one of the first steps to a expanded universe. The have changed the skybox and I suspect the now fixed asteroid bug was related to this future feature.

As I mentioned in the forums we have changed the map over to Creative. With the recent updates things have been getting a bit unstable between updates and hotfixes. The last issue we had to deal with was the ownership bug. I also expect the game to become even more unstable now that they have started implementing the expanded universe.

So, because of all this, the server will most likely stay of Creative for now. This will allow players to test new updates and build without having to loose hours of work (Blueprints F10).
