Didn't they split Cuba and Hispaniola in two in CoAS too? They must've had a reason for that. This might be it.
I still don't have that game, so I wouldn't know. But it does sound plausible.
In other news, I've exported the Cartagena island, seabed and "refl" models to test in the game... and starting a new game to visit the island, there's nothing there.
The first time, I just encountered a load of sea foam in the place of the former island, complete with collision (??!) and no island.
I then deleted the foam files to force the game to generate new ones, which it did, but still no island, and now no visible foam either.
So then I rotated the island locators to see if that would make a difference, but apparently not. I
assume everything has moved, but I don't have any visual references to confirm that.
All I CAN see is the stock fort floating in its position. And to confuse things further, System.log claims the island has no sea bed... but the model IS in the folder.
Needless to say, I'm stumped. The island export worked properly, and it looks good in GM Viewer and TOOL. Here are the logs, though I'm not sure they're very helpful.
