So I boarded a couple of invader vessels and got the normal boarding message of an amount of prisoners taken and interrogations being carried out. Due to the condition of the vessels I had to put tem in a hanger to bring back for dismantling, however I cannot see any prisoners on either the original craft or the carrier vessel. Do the prisoners stay on the main craft, get moved to a carrier when put into a hanger, or do spoiler races simply vanish into thin air upon being taken prisoner?
