Deskrawl Save File and Lost Items: Where Saves Live and How to Back Them Up

Deskrawl stores your progress as a plain JSON file plus two folders, and takes an automatic backup every 3600 seconds keeping the 5 most recent copies. Cloud save is real and shipped — patch 0.1.9 added it on June 16, 2026, and the store page still lists Steam Cloud. What does not exist anywhere is an official answer to the question you actually came with: why the chests were there when you logged in and gone after a 409 threw you to the main menu. File layout below comes from the shipped 1.0 build; the disappearance is labelled as an unconfirmed player report.

The four questions, answered before anything else

What the save file actually is

The 1.0 build does not use Unity's opaque player-prefs blob. It serialises plain JSON through a three-layer structure, and the third layer is what makes a deleted chest a deleted chest.

A golden chest is not stored as "one chest." It is a SavedRegistryEntry carrying a List<SavedChestContent>, and each SavedChestContent holds a BaseItemId, ItemLevel, Rarity, Modifiers, an InstanceId and a SocketCount. When a player says a chest was deleted, at the data level they mean rows of that shape stopped coming back. On top of this sit two character modes — CharacterMode is exactly Local or Online, and SaveSystem.MaxSlotsPerMode is 4, so four slots per mode. Since the September 28 launch-day hot fix, new characters default to Online Mode, which runs through a different save path than a local one.

The backup system, in numbers

Read those as a promise the build keeps, not a guarantee. A one-hour rotation holding five copies puts your worst recoverable window at roughly five to six hours of play — and only if the backup landed and only if you go and get it.

The developer has acknowledged this area twice, both times in beta:

Official source: 0.1.13f — Bug Fixes, July 17, 2026 Fixed crashing during save sometimes cause corrupted save files. Moved backup saves to a more secure folder.

Official source: 0.1.9 — Resizable/Draggable Window, Cloud Save, Buybacks and More, June 16, 2026 Cloud Save

That "more secure folder" line is the beta-era counterpart of the data_backup constant. Save corruption is a previously patched failure mode, not something anyone invented.

Symptom, stage, and what to do in the first five minutes

Every row is a real field report. The quotes come from the linked threads; the second column is my reading of which stage the symptom points at — the part to treat as inference.

That last row matters. The loudest thread in this cluster — fifteen posts, ending with a player saying he would stop playing — mixes two different failures. Ground loot at the end of a run is a designed round rollover; a chest inventory deleted on a 409 is not, and nobody has said which is which.

What the build says about that error, and what it does not

The transcribed error and the shipped code line up in a way worth stating precisely — the difference between a guess and a lead you can hand a developer.

The vocabulary in that error — items the server did not issue, duplicates, no server instance id — is the vocabulary the game's own code and text use. An observation about two artifacts, not an explanation.

What is officially confirmed about lost progress is narrower and more useful:

Official source: 0.1.13b — Improve stability & various fixes, June 27, 2026 [Online mode] Fixed treasure chests causing various disconnections and lost save. Treasure chests now also can only be open in town.

Official source: 0.1.13e — Stability and Fixes, June 30, 2026 [Online Mode] Added auto save while in town [Online Mode] Reduced redundant saves that increased risk of disconnection [Online Mode] Fixed occasionally revive in town causing save loss.

Chests are town-only by official rule, and town autosaves exist. Those narrow where a failure can hurt you, and are the closest thing to a cause the developer has published.

What patch 1.0.0g actually fixed

The first post-launch patch shipped September 29, 2026 and is still the latest release as of this writing.

Official source: Patch 1.0.0g — Various Improvements and Fixes, September 29, 2026 Added Stash All/ Take All button in storage panel. Fixed a few cases where cheat detection handed false bans. Loot drop system now guarantees even chance per equipment slot

Read the absence carefully: 1.0.0g does not mention save corruption, 409, invalid_save or item loss. Full archive in Deskrawl Patch Notes. Item loss and a cheating flag are separate systems — 1.0.0g fixed several false bans, so false positives are real in this codebase, but no lost-item report in the threads above contains a ban message. Appeals go through deskrawl.com/support, which authenticates via Steam OpenID.

One habit shrinks the blast radius: loose inventory items are rows in a file rewritten on every save, and the auto-sell, auto-salvage and auto-dump-to-carriage nodes move drops out of your bag without you being there. Not a fix, but the cheapest way to reduce what one bad write takes with it. Unlock order in Deskrawl Life Skills Tree; first-hour sequence in Deskrawl Beginner Guide.

FAQ

Where exactly is the Deskrawl save file? Community-reported as a Data folder next to the game executable, and the build backs that up with the SaveMigratedToInstallDir_v1 flag plus folder constants data and data_backup. No absolute path has ever been published and this guide will not write one for you. Verify the community answer against your own install, then copy the folder before you need it.

Can I get my deleted chests back? There is no published restore feature; "restore" and "rollback" appear zero times in all 26 official announcements. Your only lever is the rotating backup — every 3600 seconds, five copies retained, in the folder next to the game. If the deletions are recent, check the save_backup_*.json files before launching again.

What is the 409 error in Deskrawl? A number players report, nothing more. The string appears in no official announcement, no store page text, and no localization string in the build. The one legible error a player transcribed reads error : invalid_save, with a second line about item instances the server did not issue. Until the developer explains it, "409" labels a symptom, not a diagnosis.

Will starting a new game delete my save? The build ships a confirmation string for exactly that case, UI.OverwriteSaveWarning, reading Starting a new game will erase your existing save. Continue? A June 2026 player reported seeing that prompt when trying to start a second character, back when the game was single-character per account. The current build allows 4 slots per mode so that constraint is gone, but the prompt is still in the build. That total wipe is a different failure from the item loss here — covered in Deskrawl Demo vs 1.0.

Is it worth playing if saves are this fragile? A buyer's call, depending on your tolerance for hours of AFK progress riding on one file. The honest inputs are the backup constants above, the fifteen-post thread where a player decided to stop, and the fact that the game has been out three days. Rest of the picture in Is Deskrawl Worth It; the adjacent connectivity problem in Steam Deck and connectivity.

Where these numbers come from

Every folder name, file name, the 3600-second interval, the 5-copy retention, the 4 slots per mode and every class and field named above were read out of the 1.0 launch build's decompiled save system (SaveSystem.cs, SaveContainer, SaveData, SavedRegistryEntry, SavedChestContent, CommittedItem, CommitResponse, PutRejected) and its UI.* localization table. Read them as the 1.0 launch build of 2026-09-28; the live build is on 1.0.0g as of 2026-09-30. Steam category data came from the appdetails API on 2026-09-30, and announcement text is quoted verbatim from the Steam news API. Player reports are community reports dating from the June–August 2026 demo and beta period rather than the retail launch. The official save path and the cause of the item loss remain unconfirmed.
