Problem with vehicles with LatestArrival set

I think there must be some kind of bug with vehicles that have latest arrival field set.

On any route, in any scenario, I have no problem with designing solution, except when I set this field.
Other than that it works awesome:)

It is very hard to reproduce that on my computer. Would you mind to boil it down to a very simple test case and send me the code? Thanks a lot.

will do! meantime, I’ve sent you a PM.
