Unexplained railway wildcard/circuit behaviour

[CactusAcolyte]

Heyo!

Not sure if the error is between the chair and the keyboard for this one, but I figured I would submit it out of an abundance of caution.

In my most recent multiplayer game (hosted on a local, headless Debian 13 Linux server with two Windows 10 clients) I've been cooking up a LTN-like implementation for our rail network in vanilla. The idea is, a constant combinator places a demand on the network, which the trains check for, and if there's not enough cargo of that type read between the trains in "Depot" and trains at drop off stations, it dispatches a train for pickup.

This worked excellently, until I tried to set up copper plates, which the trains inexplicably refuse to pick up or drop off.

I attempted to troubleshoot it, but exhausted my ideas. Same issue appears to happen when running the save locally on Windows 10. Please advise!

Constant "demand" combinator.

>did you try turning it off and on again.

Have you checked the spacing between [copper plate] and pickup in the station name?

Yup, three or four times. Weirdly enough this one started working after putting down a different, separate station. Not sure what the problem is in the save file game.
