[bug] v1.2 Ghost Ship - Crucible

I was playing Crucible today and the AI got to the west ship first.  However it appeared to have a hero stuck on the ship.  The ship never moved nor did the hero - and if you attacked the ship it sunk and then re-spawned with the hero inside it.  After this I ignored it but later in the game another AI I was on friendly terms with decided to start attacking the ship and their army just sat there attacking it over and over again when the ship re-appeared every turn.
