PlanetsCentral

I recently tried to use the PHost mission Beam Up Multiple via the beamup command, but the turn checker keeps telling me no matter how I format the command that it's invalid (sorry, I forgot to copy-paste the exact error wording). AllowBeamUpMultiple is enabled in the game. In this case it was over an unowned planet (which meets the definition of friendly planet). I've tried various variants, such as (beamup 123 Tmax Dmax) or (beamup 123 T100) and nothing I've tried works.

Is this a known issue?
