I've noticed something strange, and I think it's a bug.

It seems that ships I've captured disappears from the warehouse, if I rehire the crew that brough the ship to port, before selling the ship.

Sometimes saving the game in the port, quit to desktop, then start the game up and load the save, the ships are back in the warehouse

huh? had that too thought my crew secretly sold it or something and found my crew iin the tavern
