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. 
I really appreciate you sending across your experiences with oil trade routing, @pattycake2021 , and this screenshot. I'd really like to investigate this further.
Can you make sure you've verified the game files since the update? This may seem trivial, but it's a quick and easy step that just makes sure all the files are present, and not corrupted. Thanks.
I'd really like a copy of your save file with this oil trade route to pass on to our dev teams to help us investigate this issue. Can you upload it to a third party file hosting service of your choice, and then send me a link? Here's our support article showing where saves are stored.
Thanks so much for bringing this up. I'll keep an eye out for your response
