Tried out Zenith and at the moment the world doesn't seem interesting enough to explore as of yet. Once they expand it with shops and other things it might we worth looking into it again, but for now I refunded it. 
Not sure when it started being acceptable to release unfinished games.

Have you tried validating your game files? I had the same thing happen to me before and steam was to blame. In the end I had to reinstall steam itself.
