Sometimes

[BlueLight]

I am having difficulty writing a scenario for the Maris Pass. As I test the scenario; I finding that the A.I. trains sometimes work and then sometimes they don't.
I am coming out of Essex Yard westbound. At the time when I hit the lead track on to the Main the first eastbound A.I. should start moving. However, the last
three attempts at running the scenario have proven dismal failures as the A.I. refuses its timed command to move.
Has anyone in the community ever come across this situation before? If so, what was done to fix it?

I wonder if this has anything to do with parts of the route being single-tracked?

This particular train is on the double track just east of Pinnacle. The scenario has worked before with all of the A.I. on both the single and double track.

Try clearing the cache and retry running it before you make any changes

I am beginning to understand why it took Lucas three years to complete the second "Star Wars" flick. I ran the scenario twice more and on that second attempt
the A.I. did as it was told, all the A.I. moved when programed to. Now that was all well and good, however, one hour and twenty minutes into the scenario
instead of going right into Conkelly as programed, the dispatcher decided that it would go left and plow into an on coming A.I. train
Computer programs are supposed to do only what they are told. This one is starting to act like my three year old grandson.
