Version of OpenTTD 1.11.0

Expected result

I expect the ships to not constantly say that they're lost

Actual result

The ships sometimes pop up with a message saying that they're lost no matter how many bouys i route them through. Even though they say that they're lost they don't act like it. They move to and from the stops I've set for them without problems and they make money. It's not all the ships that do this, only the ones that travel long distance. I do place bouys if they have to travel far.

Ship says that it's lost

Ship leaves oil platforms full

Makes it's way towards refinery

Unloads at refinery

Makes it's way back without problem

Steps to reproduce

Create long distance lines for the ships and after a while there will pop up a message saying that Ship#X is lost.
