Developer Dogubomb has released Blue Prince update 1.009, which the studio refers to as patch 1.05. This is another patch aimed at technical fixes, with the primary issues targeted such as save corruption and also mission-related bugs.

Same as in the game’s other patches, there are spoilers with some of the fixes, which is why we’re warning those reading this to proceed with caution when scrolling down below for the patch notes.

Blue Prince New Patch 1.009 Applies Fixes Related to Saves, Various Mission Blockers and More

Save Corruption & Loading Freeze Fixes

Here’s what Dogubomb has to say about the patch:

“We’ve identified and addressed several edge cases that were causing save file corruption, resulting in a loading freeze when accessing the main menu. Unfortunately, if your save file was affected by these issues, we are sorry to say that means it is corrupted and irretrievable despite our best efforts to find a way to restore it.

This update also includes multiple fixes aimed at preventing these corruption cases from occurring in the future. Several code checks have been added to reduce the chance of corruption including redundant checking of the validity of the save before writing it. Additionally, we’ve implemented an automatic backup system: if the primary save becomes corrupted or lost, a backup save will now load instead.”

FURTHER CHANGES IN THIS PATCH LISTED BELOW (SPOILER WARNING)

  • Fixed a bug occurring when consecutive Parlor boxes were opened too quickly.
  • Fixed an input recognition issue on keyboard where \[Right Arrow] and \[A] were incorrectly interpreted as CONFIRM in certain cases.
  • Corrected some minor magnification issues and inconsistencies in font usage in the following locations – Library, \Master Bedroom\, \Vault. \
  • Unified all instances of ‘Mary Matthew’ to a consistent spelling. (One instance had a typo.)

LATE GAME SPOILERS

  • \You can now reset rarity changes that you have made to your floorplans. The method is explained in the Conservatory menu as floorplan rarity can only be reset in the Conservatory).\
  • \The doors powered by remote power boxes are now opened by button press instead of unlocking automatically. These doors will remain permanently unlocked after being opened.\
  • \A trunk in the Treasure Trove incorrectly displaying the moon symbol has been changed to the sun symbol. (A blue memo was incorrectly being labeled as false.\

We also have corrected a few oversights and bugs in the room drafting logic. Below are listed a few of the resulting technical corrections that may be of interest.

  • \Master Bedroom will no longer erroneously appear in places other than the East Wing (Rank 9 related bug)\
  • \Fixed a narrow bug permitting Foundation to be added to the draft pool after repellent use before 7 days had transpired.\
  • \Foundation will no longer be drawn with as much frequency on Ranks 2 and 3\
  • \An oversight in outer room drafting logic has been corrected concerning day one and outer room rarities have been slightly flattened across the board.\

Don’t forget, the developers announced that patch 1.10 is the final content update for the game, though there’s no release date for that yet.
