Mayday: The Survival Island

Bugs and their patches

Quick answer

Bees, duplicate puzzle pieces, the disappearing alchemist machine, negative stove fuel and the Kraken travel lock are all fixed. Retroactive achievement unlocks arrive on load after the 7 November patch.

Most of what looked like a broken game in the first week was already fixed by the second, so the useful thing is a map from symptom to patch.

Every figure below is checked against Pequi studios announcements or Steam's own endpoints on 2026-11-09.

Almost everything that looked broken in the first week was already fixed by the second. The map from symptom to patch, so a live bug reads differently from one already fixed on an old build.

Three that cost you a run

The alchemist's machine. It could disappear, and the 9 November fix does not restore it where you put it: the machine can now be found inside the cave. Built one and watched it vanish? Where it went. The most consequential fix on the list, because the station is late-game and expensive.

The Kraken travel lock. After your first conversation with the Kraken, players could get stuck and become unable to travel at all. A soft-lock on the entire travel system, live for three days. Anyone who stopped travelling after meeting the Kraken was not doing anything wrong.

Achievements not granting. The 7 November patch fixes this and states the remedy: update, then load your save, and any achievement you had already qualified for unlocks retroactively. A 1,000-value meal cooked in the first week without the achievement will be there when you load.

Self-service repairs

Two of the fixes come with player-side instructions rather than patching existing saves.

Duplicate puzzle pieces. If you already have duplicates from the buried-pieces puzzle, drop them on the ground and pick them up again. They sort themselves out. That instruction is in the 5 November announcement.

Retroactive achievements. Load the save on the current build. Nothing else is required.

When it is still wrong

Check your build first. The version number has been on the main menu since 6 November. No version number means a build from before 6 November, six patches behind, and most of this table does not apply.

Then check whether the symptom is on this list. If it is not, it is either new or it is not a bug. The 9 November patch fixed a long list of small things, and the absence of an item from that list is meaningful: it means the developer has not seen the report.

Three false alarms

Three things that get reported as bugs and are not.

The raft not launching. It needs food in your inventory. The raft page covers it.

Dying and losing your gear. That is the intended behaviour on Normal and Hard. It does not happen on Easy since 6 November.

The hammer not moving furniture. Since 7 November, moving is a native action with no tool equipped and the hammer is demolition-only. The new design, not a regression.

Oldest first, if you are patching in order

The symptoms above are easier to place if you read them chronologically, because several of the fixes are follow-ups to earlier fixes.

8 NovPerformance rewriteThe root cause behind several earlier bugs
9 NovComfort on moving buildings, Kraken travel lock, alchemist's machine, respawnsSecond-order effects of the week's changes

Two entries on that list are fixes to bugs introduced by earlier patches, and the studio says so in the announcements. Worth knowing if you are judging build quality: the trend across the week is down in bug count, but the mechanism producing new bugs was the patching itself.

Reporting one

The patch notes repeatedly credit player reports, and the 8 November post thanks players who sent save files so the studio could reproduce specific problems. A useful report includes the build version from the main menu, what you did immediately before it happened, and whether reloading changes it. The same information produced the fixes in the table above.
