I am on the xbox 360. I was patroling the cosmodrome for the 6 patrols bounty and halfway through a patrol I was kicked to orbit with the lionfish error. When I went back to the cosmodrome I summoned my sparrow halfway up a hill abd fell through the ground. I didn't die but was trapped in the spaces between the ground and tunnels. Returning to orbit got me out and when I returned there didn't seem to be a problem. So, it seems like a fluke but I felt I should mention this. If anyone else has had this happen you can reply. :)
