@ubi-thrupney I grew impatient because I wanted to play so I started a new game. So far it's working as intended but I did notice others having the same issue. I will post if I run into it again.

@rtwpa this fix also worked for me but I had to move both the port on the receiving island and also the accepting one. I hope this issue is fixed soon though. I'm not fond of where I had to move them to. They are a bit inconvenient and my ships have to travel further but at least it's working now. Unlike others with the same issue mine seem to be only with transporting oil. Also I have only run into the problem on Cape Trelawney. Thank you so much for sharing the temporary workaround. The game is almost unplayable since most of it involves some kind of supply transport.

I've deleted the route and redone it several times. I've moved the route to try to make the ship avoid it but no matter what I do the ship ends up stuck in some corner of an unclaimed island to the right in the screenshot. Routing is making the ship go partway out and then turn around in the middle of nowhere and get stuck at that island. Routing is terribly broken.

@ubi-nacho yes I've not had a problem

@ubi-theberry No change. It has to be a glitch or something. I started a new game with the same seed and it worked fine. Weird

I have enough steel beams, wood and influence to settle this unclaimed island but the port doesn't pop up for me to claim. I've tried sailing back and forth and restarted the game but I'm still running into the issue. It's the only island that does this. I can claim any other island I sail to.
