Thanks for this, there was an issue handling conditional jump orders which caused incorrect times in some circumstances, this affected road vehicles 9 and 10. This will be fixed in the next release.
Vehicles being expected to arrive late appears to be correct though. Your vehicles are not timetabled, which makes it more difficult to see what is going on, however from the non-timetabled travel times, departures for dispatch schedule 3 are expected to arrive at the start of dispatch schedule 4 shortly after their departure slot time, and therefore can be expected to depart from there late, this is also the case for dispatch schedules 4 and 5. Improved tracking of lateness estimates across scheduled dispatch orders was introduced in v0.65.0.
Legendary! Thanks for looking into this and for pointing me in the right direction to make it all work - much appreciated. Ross.
