From what I have read in other posts, this is not exactly a "bug", but a thing to prevent leaks from patreon playtests. It is a thing happening to tons of people, but it should be fixed within a few days. As far as I am aware, devs were just being cautious about leaks from Patreon and stuff, though I could be wrong about that as I only got that information second-hand from another post in a different topic.
Hope this helps!
p.s.; I would suggest that, if this bug is a big hassle, either wait it out for a few days whilst this Mars thing is removed, or go back and play 0.7 whilst we wait for the update. Remember that the current 0.8 version is labelled as a test version, so of course not everything will be fully up to par. Again, hope this helps!
