Blue Prince Patch 1.7.3 Irons Out Colliders, Softlocks, and Blessing Errors

Raw Fury's Helen has pushed Patch 1.7.3 for Blue Prince, a focused maintenance release targeting collision geometry, softlocks, and several mechanical edge cases — some of which touch late-game content.

What changed

• Collider fixes across multiple rooms: trophy spawn points in the Showroom, Tunnel, and Pump Room were corrected; dig spots throughout the house are now easier to trigger; a desk drawer can no longer be clicked from the wrong side.
• Basement safety received two additions — a collider to prevent players from clipping through the floor near heavy machinery, and adjusted geometry to close a narrow softlock path.
• Softlock resolved when digging up a buried hint after earning a trophy without collecting it.
• Guest Bedroom upgraded floorplan mechanics had a large number of corner-case bugs fixed.
• Item spawning: a blue item now correctly appears when its room is drafted as an outer room; a rare bug that made the Toolshed appear to hold only one item is resolved.
• Blessing economy: Three Day Blessing gold amounts for the Tinkerer and Chef have been swapped to align with their intended thresholds, and the blessing list in Drafting Strategy has been reordered and reformatted.
• The Kennel's effect in The Foundation — described as an elusive, long-standing bug — is finally fixed.
• Library book (ANC) lighting and cover coloring corrected; Study letter page-turning made more intuitive.
• The right-mouse icon has been restored to the action UI.

The patch also carries a separate challenge mode and speedrunning changelog, though the source text was cut short before those details could be captured.

For players deep in Blue Prince's late-game loops, the Kennel fix and Guest Bedroom corrections are the changes most likely to have been quietly disrupting runs.
