JOONAS not delivering? Check capsule catcher groups

Locate the actual blockage

First look at J.O.O.N.A.S. to open its information panel and check whether its bin is full. Official patch 1.0.4 says the full-bin gauge flashes red, and the robot continues working without nearby players. Wikily, a community source rather than our own test, says a robot with no capsule catcher waits with a full bin. If there is no catcher, supply that destination first. If one exists, inspect the destination instead of assuming the robot must return to a dock.

Check the group, then the capacity

Official patch 1.0.5 says capsules target the emptiest catcher in the nearest group, with catchers within 100 m of each other forming a group. Once every catcher there is over 80% full, deliveries move to the next group. Patch 1.0.4 increased catcher capacity to 100 kg. Our diagnostic suggestion is to inspect all nearby catchers and their outgoing belts together. An uneven pair is not sufficient evidence of failure without checking the installed version and the actual group arrangement.

Distinguish an old bug from a current symptom

Do not use old dock-trip advice as the expected workflow: the official notes say JOONAS launches capsules while moving to its next sector. Update 1.0.5 also fixes distant hexes stuck at 99.9% and capsule packing failures in large bases. If a symptom persists after updating, record the version, robot-panel state and catcher arrangement for a bug report. These notes identify shipped fixes, not a guarantee that every similar symptom has disappeared, and this guide has not independently reproduced your save.

Choose local cleaning or whole-Moon coverage

Wikily distinguishes dock-based vacuums from J.O.O.N.A.S. Robot vacuum Mk I costs $250, covers 19 hexes around its dock, carries 15 kg and has a 100 kg dock store. Mk II costs $500, covers 37 hexes, carries 40 kg and has a 300 kg dock store. Their vacuums head home at 98% bin capacity; the dock packs up to 1 kg per capsule onto a belt. A full dock and a full robot bin are different places to inspect.

J.O.O.N.A.S. costs $20000 in the same community table, carries 60 kg and works across the whole Moon instead of a dock radius. That broader scope does not replace its capsule catcher requirement. Choose a robot for the area and delivery route you can actually support, rather than treating the higher purchase price as proof of the best return.
