Well, let me go back and explain all that happened yesterday. Maybe somebody can make sense of it all. Like I said, I spent half a day Friday and all day yesterday inserting Trackmarks all across my route, and placing them in all my AI trains instructions. Worked very diligently and carefully, trying hard not to make any mistakes on track maker placement and inserting the "Navigate Via Trackmark..." instructions to my AI Trains. I even drew a map of the route, showing all stations, towns, industries, etc.
Well I finally finished with all that work and went to drive the session. The trackmarks didn't seem to help much; AI Trains would go right over the trackmark but the trackmark wouldn't delete from the AI's instruction list. This didn't happen all the time. Some trackmarks would delete and the AI instructions would show the next trackmark or industry, ststion, etc. down the line.
I saved my work a bunch of times. When I finally closed the session and went to the session/route menu, I decided to delete some older sessions since I knew I wouldn't be using them. I began to delet the old saves, then suddenly, the whole two days worth of sessions just vanished and I was left with the original three sessions from a month back. What happened? Why did it delete a bunch of sessions all at once? I blame that dang Layers crap. They have caused me so much grief ever since they were introduced. I was working in the route/session using the edit in classic surveyor mode when adding a trackmark, and editing in Driver (when I wanted to add a trackmark instruction to the AI Train, since you can't add/remove instructions in the Edit Session tab anymore).
AI Trains are my whole world in Trainz. My joy is sitting in the conductor's chair and watching the scenery go by. I'm not much into driving the trains by myself. But if the AI Trains don't work like they're supposed to, I get very frustrated and discouraged. That ruins my love of the game.
See you guys in American Truck Simulator!
