Developer Housemarque on Thursday released the new Returnal patch 1.3.4. The patch is now live for all PS5 users of the game. The good news is that patch 1.3.4 fixes the save game issue caused due to patch 1.3.3 including the Trophies, and Keyboard Exploit issue.
Also note, that the latest Returnal patch 1.3.4 reverts to a previous stable build (1.3.1), addressing a known Trophies issue, and fixing a keyboard exploit. According to patch 1.3.4, players with corrupted save game issues due to patch 1.3.3 can now safely continue their progress after installing Patch 1.3.4, without the need for using a backed-up save game.
Below you can find the latest info on other scenarios for game-saving issues after applying patch 1.3.3 and which have been investigated in the Returnal patch 1.3.4.
Unfortunately other save games will have been effectively “deleted” by Patch 1.3.3, with their file size reducing to 0KB. These save games are not directly salvageable by Patch 1.3.4, without a backup save game available.
In those cases, please try using a backed-up save from PS+ if available, after installing Patch 1.3.4. With an intact save game from PS+, players can safely restore and continue playing with Patch 1.3.4 installed.
Depending on the console settings, the cloud save may have been overwritten by the “deleted” save game noted above. If this is the case, progress will remain unsalvageable, even with Patch 1.3.4.
