If Apocalypter will not let you sleep while fatigue is disabled, check that you are running the release version with the September 26 hotfix. That patch fixes this specific problem and removes the minimum tiredness requirement for sleeping. Waiting for a particular fatigue threshold is therefore not the current answer to that patched restriction.

The official release announcement also fixes a case where canceling sleep left its interface on screen. These are separate symptoms: a lingering interface is not the same thing as sleep being unavailable.

Follow the symptom

  1. Confirm the version. Compare your installed version's update history with the September 26 release announcement. A demo discussion may describe different rules.
  2. Check the fatigue setting. If sleep fails specifically when fatigue is disabled, this is the symptom named in the patch. Verify the game has received that update before changing unrelated settings.
  3. Separate entry and cancellation problems. If sleep begins but canceling leaves the interface visible, note that cancellation is also covered by the same hotfix.
  4. Keep a precise report if it persists. Record the version, whether fatigue was enabled, whether you were starting or canceling sleep, and whether the problem occurs after loading a save. That gives a report more diagnostic value than simply saying sleep is broken.

What the patch guarantees—and what it does not

The developer describes save files as compatible, while warning that some fixes appear only for newly spawned items or in a new game. The announcement does not say which of those conditions apply to every sleep case. Do not delete a save on the assumption that restarting is required.

These notes do not establish every sleeping location, interaction key or amount of recovery. This is a fix checklist for the confirmed release symptoms, not an invented full sleep mechanic. If the checks do not match your problem, use the game discussion board and keep your existing save.
