Hello,
i've got a strange effect with wildcard interrupts in train schedules. I have a train group with 13 trains. These have a station "Erz" in their schedule, which is a group of pickup stations for different ores. The other stop is an interrupt, telling them to return to the main station dedicated to the ore they have loaded.
Ever so often, a random train rises a "no path" error. This happens independent from the specific ore they have loaded. The only way to further use this train is to drive it manually to its drop-off station and set it to automatic when it's empty. So far, this never happened to more than one train at a time. But each time all trains are set to automatic, this happens again within five minutes or so.
In this example, it happened to a train with coal. Here the drop off station:

The trains configuration:

And an image showing that there is a path to the destination:

I hope someone can help. I can provide the savegame if that should be of use.

Thanks in advance

There is no path to the destination as specified in the schedule. That is, there is no destination named "<item_wildcard> Hbf".

The wildcard should have been replaced by the actual item in the train's storage before it was added to the schedule. That is, the destination should have been "<coal_icon> Hbf".

I've never seen the wildcard system fail like this. Not when you've checked to see if the train is full.

Yes, that's exactly the point i don't understand. And i'm pretty sure that never happened in version 2.0. I just double checked that there are no erroneous spaces in station names or in the interrupt target.
At least i just found the edit button in the name of the wrong station. With that i can choose the destination manually and so correct the error.
