Moon Sweepers J.O.O.N.A.S Stops Working: Version Checks

Match the symptom before changing the base

What you see	What 1.0.4 changes	Useful observation
Stops only when you leave	Continued work without nearby players	Version; whether it resumes on return
Circling near buildings	Revised routing; inaccessible hexes skipped	Obstacles and displayed sector
Bin gauge flashes red	Revised full-bin indicator	Information panel and capsule activity
“Could not pack a capsule” despite supplies	A specific machine stall is listed as fixed	Message, machine type, power/material display

The last row is a machine error. Not every capsule warning has the same cause as a robot’s distance-related stall.

Read its current task

Version 1.0.4 adds robot activity on the map, per-type visibility toggles, a sector readout and an information panel when looking at J.O.O.N.A.S. Distinguish no cleaning, no delivery and working in an unexpected sector.

The announced work cycle also changes: finish a hex from the outside inward, then launch capsules toward the nearest catcher while continuing onward. Older advice assuming a mandatory dock trip can describe obsolete behavior.

A short diagnostic sequence

1. Confirm the installed version before using a launch-week workaround.
2. Observe one robot’s map activity, sector and bin indicator before rebuilding a line.
3. In co-op, compare host/client observations; check shared systems.
4. Preserve a world backup before experiments that change buildings or files.
5. Report persistent symptoms with the version and observations. A published fix does not prove your particular world is healthy.
