PlanetsCentral

I am not aware of any problems (yet). With this little information I can only speculate. Are you perhaps using a planet Id in the command?

I have been able to replicate the problem in North Star 8 (where I first saw the problem), but not in other games. Perhaps there is something odd with the game configuration that causes problems with the beamup command?
