Hi, I wanted to play and test new version of game but my save file isn't supported and I don't know why. I know that I wasn't playing a lot of time - this save is from 17.02.2026 so it was a little time ago but I think it wasn't so so long ago. Can I do something to open this file and continue this play or there is no possibility to recover it and I need to start game from beginning?

1. [SPZ2-6192] — ✨ 82% similar

Save games from 1.0.1-rc1 are incompatible on the 1.0.0-rc3 build.
To Do • Priority: Medium • Fix: None • Game: 1.0.1-rc1

Savegames created in the 1.0.1-rc1 build cannot be loaded in the older 1.0.0-rc3 build. To reproduce, create a savegame in 1.0.1-rc1, then attempt to load it in 1.0.0-rc3. The savegame appears blacked out and displays an "unsupported savegame" message. Expected behavior is that savegames should only become incompatible between versions after a planned compatibility bump.

[0.0.9 RC4 crash loading RC3 save]
Done • Priority: High • Fix: Version 0.0.9 • Game: 0.0.0-alpha23.2 • Resolution: Done

A slightly edited savegame that worked in version 0.0.8, RC1, and RC3 crashes when loading in RC4. The save belongs to a high-level player (Operator Level 753) and would crash in RC2 but worked fine in RC3. The issue has been fixed, though FastBeltPathLane sanity checks still fail when loading the savegame in Editor or Debug Build mode.

Fatal Error: Savegame does not load (from Friday)
Done • Priority: Highest • Fix: 4 - Early Access • Game: 0.0.0-alpha23.1 • Resolution: Done

Savegame files from Friday with 100% completion fail to load with fatal errors. The issue occurs when trying to load these saves, with errors indicating the menu Savegame is below the minimum supported version (1032 vs 1082) and null reference exceptions in FluidPortSystem. Savegame files at 5% completion with 100 Structures load without issues. The problem may be related to Mods, though all old Mods and Savegame files were removed from the drive. The issue has been verified as fixed after a ...

Fatal error loading from 0.0.9-rc1, but loading from 0.0.8 is OK
Done • Priority: Highest • Fix: Version 0.0.9 • Game: 0.0.7 • Resolution: Done

Fatal error occurs when loading savegames created in version 0.0.8 or 0.0.9-rc1 on RC2 build. The game throws a System.IO.EndOfStreamException indicating it cannot read beyond the end of the stream when attempting to load the backup savegame file. This prevents the game from initializing and makes the savegame unloadable. The same savegames load successfully on the latest internal build. A fix was pushed by lorenzo that should resolve the compatibility issue.

[0.0.9-rc5] Unable to load a saved game
Done • Priority: High • Fix: Version 0.0.9 • Game: 0.0.7 • Resolution: Done

Player on Windows 11 with Direct3D11 was unable to load multiple Savegames in shapez 2 version 0.0.9-rc5. The log analysis revealed three types of failures: some save files had invalid Base-64 content, others failed to decompress due to DEFLATE stream errors or GZIP CRC mismatches, and one backup failed because it contained an invalid color code "p" during Shape Code parsing. The invalid color code caused game initialization to fail completely. The issue has been fixed in master and version 0...

Savegames Failed to Read
Done • Priority: Highest • Fix: Version 0.0.9 • Resolution: Done

The game was unable to read any Savegame / Save / Save File / Save Game files in shapez 2 / Shapez 2 / shapez2 / the game. This issue prevented players from loading any of their saved progress or data. The bug was initially not reproducible by the development team, but after the affected player provided a rough reproduction scenario, the issue was identified and fixed. The bug has been verified as resolved.
