Ships Falling Through Planet
WHAT IS HAPPENING
A rover or a non-station grid will start falling through the planet and be lost forever. Sometimes it starts with parts of the ship slowly drifting away from the rest of the ship. Other times it seems that the ship just hits a "pothole" and falls through.
WHAT SHOULD HAPPEN
Ships on the ground should not fall through the ground.
HOW TO REPRODUCE
We haven't been able to figure out how to reproduce this one. It seems to happen at random. We've lost one fourth of all rovers built on our server this way.
