Mutineer Rock bug?

Sorry if this has been brought up already, or if it's a different island or if it's supposed to look like this but Mutineer Rock on my map compared to the ship map is different some islands aren't connected etc. Is it supposed to look this different or have i got the complete wrong island, i'll add a imgur link to images (the imgur folder is hidden and can only be seen through the link) Again sorry if it is supposed to look like this or i'm just being stupid Images
