Weird bug

[Maenethal]

Occasionally when I am exploring a planet, the game will freeze for a second and mountains will appear around me. They disappear as I move away from them, and seem to stay on the edge of my vision. I have died a few times because it kept me from getting to my ship.

Sounds like the same thing as this ...

R201 Planet Type suddenly changed?

I was walking around a planet when it suddenly changed from a barren icy / rock landscape into an acid landscape with vegetation. Mountains disappeared within sight range. [EDIT] When you load the save file the terrain changes stop, but the changes that have already taken place remain.
