I replied to your question a few days ago. I tell you the same thing now, don't use POTC since it's an unfinished port and it won't work with Maelstrom properly. Instead, download New Horizons which is basically a same game with some improvements.
I appreciate your answer, but it is not the case that New Horizons is basically the same game with improvements. To give one example, many of the new towns look awful in my opinion. They look completely out of place both historically and culturally.
Also, I would like to point out that the specific problem I am asking about was already fixed in a previous update, and has now crept back in. It should thus not be hard to fix again.
