Found a really bizarre planet yesterday. Not sure if it was a glitch, but it had all these weird rock formations on it - they had a pyramid, and then a square of rock hovering over the pyramid peak with a square hole in the centre, like a cube halo.
They were everywhere too, not just one or two...
Still playing this a fair bit. Found a really harsh planet with freezing temperatures, and even colder storms. Even with a cold shield I could only last a minute outside. Racked up a few Sols before I got bored of huddling underground though.
Then I found a planet with no fauna at all, which was weird. Proper desert like.
