Worth nothing that the patch notes have late-game fixes that will spoil the game for you. If you’re planning to check out what got fixed, there’s the initial bug fixes, and then the fixes that have spoilers in them are nestled below it. We’ll add another warning so you can scroll or click away.
Blue Prince’s Latest Patch 1.004 Fixes Game Locking Up and More
Here are the bugs fixed in this patch that are safe to read:
- Added redundant video files of our cinematics compatible with more Steam Decks. This is the fix responsible for the increase in the game’s file size.
- Fixed camera lock that occurred while reaccessing the lab machine on subsequent days after activating it / solving it.
- Misc. typo and text format fixes.
- Fixed major bug causing rarity and directory data to be read from previously accessed save files. This bug would cause rarity changes to inadvertently carry over between save files. This bug also potentially caused some uncommon and rare rooms to appear less frequently than they should have for some players.
SPOILER WARNING!!
The fixes below are unmarked but will spoil parts of the game. Proceed at your own discretion.
LATE GAME SPOILER
- Fixed softlock that occurred while accessing the blueprint menu or systems menu while traveling by boat
- Fixed hardlock that occurred while attempting to unlock a locked door found outside of the house with a basement key.
- Fixed bug that would rarely cause only one item to appear in the TOOLSHED.
- In a special room added by the drafting studio, C_s__o , the use of Coin Purse had been prevented. However, due to a bug, one machine was still able to exploit the use of this item. We are sorry to report this has been fixed and Coin Purse no longer works while playing games in this room.
If you haven’t played Blue Prince yet, it’s one heck of a puzzle game. Over on Open Critic, it has a score average of 89 based on 68 reviews. Our review of it speaks very highly of the puzzle game, stating, “Blue Prince was worth the wait. It’s easily the best first-person puzzler since Portal (or its incredible sequel). With countless mansion layouts, dozens of rooms to discover and best utilize, plus a nearly constant drip-feed of lore content to absorb, this is an ideal first game for any studio.”
