b598 I haven't switched off experimental
This belt-fed 4-module station is usually operating normally, but it had two instance of what I think is a bug, I hope it's not just user error. I'm pretty sure I saw the station working normally in between these two instances.
expected behavior: station named "Tallman Rock Platform" fills with rock, a train in its network comes to empty the station and bring the rock to the stacker tower at "Stacker Rock Platform"
observed behavior: station capacity remains at 958/960. Two modules of the station fill with rock, and the other two (with empty belts attached) flicker between 238/240 and 240/240. With no intervention, no train arrives and the capacity remains at 958. But if I reload the save and mess with the station a little (switch it from load to unload and back) it will fill to 960 and call a train. This 'fix' doesn't seem to be consistent so I don't know if it's really doing anything, but reloading the save and leaving the station alone does seem to consistently result in no train arriving.
I'm uploading two saves where it happened. In the earlier save, a train isn't expected to arrive at the time of the save because the Stacker station isn't empty, but at the end of the ingame year the Stacker station is available and the mining station still isn't getting a train.
