Self-Feeding fuel station causes train logic to break

I'm not sure when it happened but at some point my coal trains stopped dropping coal at my refinery. I'm using steam locomotives and this was one of my first starts so I set this up to be self-refueling.

The trains were able to see and service other stations. Pausing/unpausing the station or removing it and re-adding it to the schedule refused to work. Eventually I just ripped out the steam locomotive refueling module and suddenly everything worked again.

This should be the save from directly before I fixed it if you want to look at what's going on.

Why do you have exclusion zones set in an area where you have uni-/one-directional tracks?
You can set a Train Limit on every/any station to restrict how many trains are queing for it at a time.

Because that was basically my first station and I was still fiddling with things.

Oh, ok, but that could have been one of the issues here.

Might be. Issue is fixed, mainly posting in case there's something weird on the back-end the devs need to know about.

Deleting that segment would have made a non-exclusive section. The problem was that it was working just fine with those exclusive sections for a while.

But yeah, that station isn't long for this world. Or at least the copper part isnt.

Thanks - there was something weird on the back-end going on! The paused train in the depot had become a bit confused and was holding the arrival "slot" for this station.

Good to know!
