JOONAS in 1.0.5: catcher groups & incomplete sectors

Understand 100 m catcher groups, the strict over-80% rule and separate 99.9% and 0% completion fixes.

Official 1.0.4 / 1.0.5 statements · JOONAS not play-tested
Reviewed 29 October 2026 · No hands-on testing

Direct answer

For 1.0.5, the developer says JOONAS selects the emptiest catcher in the nearest catcher group. Catchers within 100 m of one another are grouped; delivery moves to the next group only when every catcher in the current group is over 80% full.

1.0.4 history: cleaning and delivery

The 1.0.4 notes introduced capsule delivery from JOONAS’s current position without returning to a dock, followed by continuing to the next sector. That release described the destination as the nearest catcher; the 1.0.5 grouping rule below is the newer documented routing behavior.

The 1.0.4 statement that JOONAS cleans without a nearby player, routes around buildings and skips unreachable hexes remains historical context. It also described a full-bin red flash and information panel. No hands-on distance or navigation test is claimed.

1.0.5: which catcher receives a capsule?

Within the nearest catcher group, delivery chooses the emptiest catcher. The developer describes catchers within 100 m of one another as grouped. Only when every catcher in that group is over 80% full does delivery advance to the next group.

The words every and over matter: this is not “one catcher reaches 80%.” The announcement does not specify a graph-clustering algorithm, ties between catchers or selection between equally distant groups. This guide does not invent those rules.

Completion symptoms are separate cases

For 1.0.5, the developer reports a fix for distant hexes left at 99.9%, without completion or payment, after cleaning while players were elsewhere. A separate JOONAS fix concerns a persistent ground patch where building was impossible.

Another 1.0.5 fix covers clean sectors incorrectly displaying 0%: they are checked when the world loads and should then complete and pay. The map also stops showing 0% where progress has not yet been measured. This 0% case is distinct from the JOONAS 99.9% case.

These statements do not establish that every 99%, 98.9% or other incomplete sector shares the same cause. Record the exact displayed percentage, installed version and whether cleaning or payment is missing. Do not delete or replace a save to follow an invented workaround.

If JOONAS still appears idle

Record the installed game version and solo/host/guest context.Describe whether the issue is movement, visible cleaning progress or capsule delivery.Record the visible bin indicator or information-panel message, if present.Note the nearby buildings or inaccessible area and the action immediately before the symptom.

Checks stay in this page’s memory. Nothing is sent or saved.

Use those observations in a focused developer report. They are diagnostic context, not a verified reset procedure. This guide does not promise that a patch, placement change or restart will resolve the symptom.
