After playing the scenario planner recently, I noticed a few bugs none of the ai trains move Any stations that are not start/end stations make me open doors on the wrong side Any control cars or locomotives on the opposite side of the train are facing the wrong direction
As said above, the first point is not a bug. They have to be selected to start either the same time as you i.e. say 15:05 or beyond. If you select an AI train to start at 15:00 when you start at 15:05, AI would wait 23hrs 55mins etc. The second and third points I agree with you as wrong-side doors and backward spawning trains happen on some routes like ECW. What routes were you experiencing this on?
Make sure there aren't any cases of AI trains causing others to go into red signals. I personally have no issues with this.
