Ive had this happen - imported a route into TS22 from older creation. The “drive to” command didn’t find the destination due to a discontinuity in the track. I found the break at one of the TS2006 style stations, didn’t appear to be broken, but I needed to re-link the track to the station splines.
I've seen it too when I've removed a station from a route I was working on and hadn't updated the driver's schedule to match. It may be a shocking surprise but it sure is helpful to know when there's something missing from the schedule rather than have AI drivers decide to stop and put up the unable to plot route to the destination message. That message, while useful isn't because it doesn't state who can't find their way.
It was set path command.
As previously stated the problem rectified itself at the subsequent openings of the route.
However a issue remains on the same siding road with one junction and length of track.
I have carried out a number of procedures in an attempt to correct the situation however issue remains.
I am able to revert to manual operation and move over the section a short distance then revert to the the driver commands.
