For the Capture Colonies mod to work properly, I had to make the game use one MORE locator than was the case before. However, I disabled that again for ships. So we'd have to see if that problem still occurs. Should be back to Beta 2.5 state on that. That is RESOURCE\MODELS\Locations\Town_Cartagena\Port\cartPort_lb.gm . Same problem applies to the regular Puerto Rico port too.
