Scenario error because of AI Driver, can't find the AI Driver

[pkz19]

So I was building out the rolling stock in the yard in a scenario. I had an AI train that was set to run a route and copied some cars from it. I accidentally reinserted extras and then when I deleted them, I left a gap so I inserted another couple cars to complete the train. When I went to run the scenario, I got an unknown error for that AI driver. I tried editing the route path to reset, but still got the error. I figured I'd just delete that AI driver and start over, but the little icon was gone. The AI driver still shows up in the timetable, but I can't find the icon anywhere. I even tried deleting the locomotive the AI driver was in, and that didn't work. Is there any way to delete a driver without using the icon? I couldn't find any way to do it from the timetable.

What a mess! My first instinct is to advise you to delete the scenario, no matter how much work you've put into it so far, and start over. Of course, that isn't very appealing. Each consist, whether driven (including AI) or static, has a specific identity in the editor from the moment that you place it on a track. The editor also assigns a unique number to each piece of rolling stock (which can be modified, but that has to be done very carefully) and duplicate numbers are not allowed. I don't know exactly what you mean by copying some cars from the AI train, but the important question is what you did with them. If you pasted them somewhere else, that created cars with duplicate numbers. What do you mean by "reinserting extras"? Reinserting them from where? Repeated copy/paste actions, insertions and deletions have obviously overwhelmed the editor.

Back to my first instinct. The editor is extremely sensitive to the kind of repetitive and redundant actions that you have taken. If you haven't done so already, make notes about what you've done so far in terms of instructions assigned to the player train and all AI trains other than this one; then scrap the scenario (meaning, delete it); start again -- preferably with a different name, using your notes as much as possible and being careful to avoid repetitions of previous mistakes. Be sure to test the scenario each time that you change it; meaning save it, click the run button, use ESC to exit the scenario, shut down TS, launch it again, open your scenario, and run it completely. If all is well, shut down TS again, launch it again, open the editor and proceed with your next edit. "Rinse and repeat." That's the best advice I can provide.
