Moon Sweepers Fully Automated Factory Basic Build ↗Factory build guide uploaded October 25 (3:35). Checked on screen October 26: at 0:12–0:14 the Build menu's Services tab lists Robot vacuum Mk I $250, Robot vacuum Mk II $500, J.O.O.N.A.S. $20,000, Capsule catcher $1,500 and Garage $200; the J.O.O.N.A.S. card says it scrubs the Moon one hex at a time, fires its dust in capsules at the nearest capsule catcher anywhere on the Moon, and without one waits with a full bin until one is built. At 1:40 and 2:00 the Production tab lists Pressure chamber $500 and Stone press $1,000; the Pressure chamber card says it presses moon dust into moon sand, up to 5 kg every 12 s, sand sells for 3× dust, and it needs 10 kW from solar panels in range. At 2:39–2:40 a stone press panel reads Dust + sand into moon stone, Power 18/18 kW, Dust · Sand 12 + 12 kg, Stone 2/10 kg.Walkthrough · checked · published 25 Oct 2026
Stone Press Input Not Working ↗Player post, read October 26. The stone press accepted dust and sand by hand but not from belts from the garage and pressure chamber, with plenty of power. A reply: the press's input ports are labelled, and they had sand going into the dust port and dust into the sand port; swapping the belts fixed it. The poster confirms that was the problem.Reported · checked · published 24 Oct 2026
Steinpresse/Zusammenführer/Druckkammer ↗German players' thread, read October 26. The poster put a splitter in front of the stone press expecting it to send sand to one input and dust to the other; instead it filled both inputs with the same product and jammed. Replies: a splitter only divides, it doesn't sort, so run one line to the pressure chamber and another to the stone press (German); put the splitter before the sand step so part of the dust makes sand and part goes on to the stone press, and every input and output on the machines is labelled (Russian).Reported · checked · published 25 Oct 2026

Stuck on 1.0.3
Clearing Steam's download cache brought 1.0.4 for one player.
Moon Sweepers 1.0.3 Patch ↗October 24. Heavily cleaned bases load again; damaged saves repair from backup or snapshot. Upgrades shared: the crew uses the host's upgrade matrix and anyone's purchase upgrades everyone. Host can kick or ban from ESC > Your Crew and unban there. Splitters and mergers built by crewmates work; they snap port to port. Machines can stand across several foundations. Vehicles work at every garage. All crewmates must be on 1.0.3 to play together.Official · checked · published 24 Oct 2026
Version mismatch, cannot join friends ↗Player post, October 26. The poster stayed on 1.0.3 after uninstalling and verifying files while a friend was on 1.0.4, so they couldn't join. A reply: clearing the Steam download cache was the only thing that worked, and 1.0.4 appeared immediately; the poster thanks them.Reported · checked · published 26 Oct 2026
