LOL this is very interesting. I saw that ship - got screens of it too - the ships OWNER, I KNOW who he is. That ship was glitched all day and it did move, but only near their island. My crew and I tried to unglitch it or move it with our ships, but couldn't. So we noticed that the ship had been opened to public. So me and a friend boarded it. We were going to try to take the wheel and port it. We couldn't take the wheel. The green circle would show, but when you hit shift to take the wheel it would turn blue but not let you actually take it. Now while on the ship the "OWNER" was AFK and pirates were on the cannons shooting any enemy ship that happened near it. Sinking them all as they ran up their bounty. (I have screens of this too along with the owner) Interestingly while I was aboard it, the ship did began to take damage. The repair holes appeared. Those on cannon got excited and ran to the holes and fixed it - once. And I was aboard that ship for 15 minutes. Trying to get the cannoneers to quit shooting the other ships ... alas it was to no avail. Hehe I did report all that were on board.
I had a conversation with the "OWNER". Asked him how he did that 'glitch'. He said he didn't know how he did it that it happened after he sank .... BUT he also said he opened the ship after he glitched and in his words "thought it was funny". (I have screens of this convo too) I found it not humorous at all. In my opinion he should have logged out. I even asked him about it, his reply, "there was someone AFK on the ship". My reply to that was it was your ship you should have then decrewed and closed the ship to friends, crew, guild and public. Then log out after the AFK person left.
I mean really folks - you can't take the bounty with you, now can you? And if you are sitting on a ship that you can't sail what is the fun in that? Just to run up the bounty and perhaps get on the leaderboard for the day? Sigh.
BTW the next night there were two more ships doing the same thing. Sitting at the island with cannoneers shooting ships and not taking damage.
