Something odd happened in a recent game. I *think* it's a bug, but not sure.

In turn 8, as Lannister, I had taken Pyke. I then moved all my troops out of Pyke, forgetting that I would lose my ship in the port if I didn't leave a token behind.
What was odd is that not only did I lose the ship, but it immediately became a GJ ship. It didn't affect anything, as I moved back in later on turn 8, but just wondered if this was correct behaviour, or whether the ship should have died?
Additionally, I didn't remember there being a rule about "home" areas automatically returning to the "owner" if they are vacated without a power token being left behind - though I'd be happy to be proved wrong and can believe it.
