I think the design of the map is excellent but I found there might be some bugs here in the game.
For me there are three problems and I think they somehow are caused by the same bug(?)
1. Cars will just disappear suddenly on the road when they passed one point. (Not LOD issues, they just disappear in front of me)
2. As shown in the screenshot, some AI vehicles are spawned/driving in the wrong direction (this shouldn't happen) causing congestion.
3. Though I had scheduled bus index count set to 85 and AI priority to 4(highest), some buses (especially at the terminus) are still not spawned even I set the time to when they should depart. (And the logfile didn't say there was a problem with spawning AI buses)
So for the conclusion, I suspect that maybe there are AI paths problem with my map? I've already reinstalled the whole file of the map twice, don't have any Sceneryobjects or Splines missing, but the problem still exists.
Anyone could check out the possible reason?
