Hmmm got a strange one....
Transferd thrue a alien gate in Sol to Wolf 1061, only a star no planets so I jumped back again to Sol, task force were ordered to Earth to refuel, about seven days later a huge ships transfer into Sol via the same Gate, it shows up as red... Getting closer to it and I find outs it about 200000 tons big but I cant shoot at it, never shows up in combat assignments... A day later a new ship appears, 1000 km/s... (Maybee a Star Swarm Queen)
Cant attack it.... Moves to MARS!?! and are now sitting above Mars doing nothing....... Anyone knows if its a bug or something els.... Checking the Diplomacy they were neutrals.... Not anymore trying to kill them before they do any significant damage to me.
By SMing it its Star Swarms
