My Sv disappeared many times when I leave it just a moment!!!! I drove my Cv to a new plant oribit, and drove my Sv to the surface of the planet(lava).When I get into the TS of the planet,and teleport to TSO of the space,and get back. I can't see my Sv,but I know it is here!Because in the Sv area I can't feel too hot. This is a serious bug，please solve it. By the way,my friend in my factions can see the Sv when the problem has arisen yesterday.
