Some advice for those who are getting the black screen crash or the editor separating
We are tracking down the cause of this now
Right clicking on GameGuru in the Steam library, click properties, then local files, then click VERIFY INTEGRITY OF GAME CACHE.
This will perform a repair on the GameGuru build, and restore any missing files.
It won't affect custom media or maps, so is safe to use.
This method only applies to the above crash and is faster than a full reinstall..
We expect to have a fix for this very soon.
