Ship Not Available!! Help

[Pirate Miranda]

Ahoy Seadogs,

I was just plundering some ships for a quest (called "Pirate Life") and I just take a Light Sloop called "Dark-Water Queen" out in the sea. So I beginning to search for the ship in diferent island to see if I can sail it. First of course is Cuba where I usally set sail-"Dark-Water Queen" was not there! It says "Ship Is Not Available", then I went to the two remaining island (that I have unlock) which was Tortuga and Port Royal. I start to click "Board" (but one different I spot is the "Dark-Water Queen" says "Board", but my other ships says "Launch"...Can anybody explain this??) Yesterday, I try to remember which island I went-Raven Cove is another island. I went to that island with my Galleon but still can't "Board" the ship. Not sure where, but something is a little fishy when I saw there ONE Shipmate on the ship!! Is someone invading my ship and taking over it? I have to search every Ocean/Server now. Hope I find who "steal" it soon! D:

Can't somebody explain how to solve this problem? Or should I contact the POTCO Team? o.o
