Bug reported on Steam (https://steamcommunity.com/app/434520/eventcomments/4630358389444089538/?tscn=1732727139)
QuoteSince the last update, the game has been having problems loading and unloading vehicles at stops. For example, trains are often unloaded and then simply stop at 0%. It also happens more often that stops are not filled with goods from factories and therefore no vehicles are loaded. If you then turn the direction of the map, it works again for a while.
I wonder if that's related to what I posted earlier this week: https://forum.simutrans.com/index.php/topic,23263.0.html
Error fixed according to steam.
