Hi, just bought the game a few days ago so I apologise if this is a silly question. 
Just was playing a game against the hard ai testing out the dark armada as vasari.  Was fighting using mainly dark armada ships and a few of my own capital ships in the mix against 2 other fairly mixed armies also of Vasari.  Combat site was an enemy planet they had just captured off me.  Was clearly losing so I thought I'll just take out the high level evacuator ship before I lose completely.  It got down to about 500 hull points when suddenly it started healing, went all the way up to full health in about 10 seconds with no "Hull Repair: **/sec" notation on its info card.  As far as I know so far theres no way to repair an evacuator ship that fast as vasari.. anyone know what happened?
