A few hours ago, I received a CN1 traffic jam report from our automated traffic monitoring system.
I arrived at the accident scene and found that train 91320 was parked in an abnormal position. The K4 signal has been opened, but the train not move. But if the train is driven by a real player, it can move normally, but will receive error messages about stopping at the station.
This issue has occurred multiple times in CN1. I hope developers can investigate why this issue occurred and fix it.
