Start by checking the version
Bring the host and all crewmates onto the same version. The 1.0.3 notes already address crewmate-built splitters and mergers; 1.0.4 expands shared belt construction further.
Inspect one connection at a time
- Follow a single material along the line and identify where it first stops.
- Check the connection immediately before that point.
- Test a short path before reconnecting the rest of the network.
- When a merger is involved, account for its alternating inputs in 1.0.4.
- Check whether the material actually reaches the deposit intake.
These are general isolation steps. We have not reproduced every conveyor fault, and we do not guarantee that rebuilding a line fixes it.
Materials arrive but the payment looks wrong
Version 1.0.3 says dust and stone delivered by conveyor pay on arrival at the deposit intake. It also fixes payment to match the intake’s displayed amount.
Compare one controlled delivery with the screen display. Avoid mixing materials while diagnosing the result. We do not have a verified formula covering all materials or every economy upgrade, so an exact earnings claim would be premature.
Still stuck? Capture a useful report
Record the host and client versions, the material, the junction type and the first connection where flow fails. A short recording is more useful than replacing the entire base without identifying the fault.
Use the game’s official Steam community discussions to report a reproducible issue. Before changing a large setup, preserve a copy of the save. Related reading: automation and J.O.O.N.A.S., co-op construction, and save backups.
