The latest release announcement verified for this guide is the September 28, 2026 hotfix. The September 26 update is also important because it changes sleep requirements, trailer attachment and several trading or physics problems. Both announcements say save files are compatible, with some fixes applying only to newly spawned items or a new game.
Read the official news feed before applying a workaround from an older discussion. The public demo has a separate update history; a demo patch is not automatically a release-version fact.
September 28: handling and discovery fixes
The developer reports fixes for objects being dropped or attached in the wrong position, wheels taking damage while being hauled, an invisible car-wreck collider, and missing Mechanic and Organic Mechanic Codex entries. The notes also cover plant lighting, batteries that could not be picked up after a merchant's death, and bats repeatedly trying to fly downward at certain heights.
These are named symptoms, not a promise that every item or physics bug has disappeared. If a problem continues, record the specific object and whether it was already present before the patch.
September 26: checks that change player decisions
| System | Release change | Practical consequence |
|---|---|---|
| Sleep | Fixed sleeping with fatigue disabled; removed minimum tiredness requirement | Old advice to wait for a fatigue threshold may not apply. |
| Trailers | Attaching a trailer detaches bumpers; rear bumpers cannot be used while towing | Automatic bumper removal is expected. |
| Suspension | Fitting a lift kit detaches the trailer | Finish the suspension change before checking the connection. |
| Trading | Fixed liquid selling failing after other items were tried in the liquid crate | Match the transaction sequence when diagnosing the symptom. |
| Physics | Fixed engines and radiators losing their physics lock after loading | Distinguish load-related behavior from other attachment problems. |
| Combat | Black Juggernaut HP increased to 6000 | Earlier HP claims may be outdated. |
The update also disables buggy fall damage for the time being and fixes persistent boss music/UI in peaceful mode. A temporary change should not be treated as a permanent design promise.
Preserve useful progress
Save compatibility means the developer did not require abandoning every existing save. The qualification about newly spawned items means an old object and a fresh one may be relevant to a comparison. It does not identify a mandatory restart for every symptom. Keep your save and report the exact conditions before trying destructive changes.
For focused checks, open sleep troubleshooting or trailer attachment. For the overall first-session plan, return to the beginner guide.
