Steam News has word on a new patch now automatically available for Puzzle Agent with bug fixes, rules updates, and puzzle updates. The change notes follow.

Fixes

• Render Layer Issues on NVidia 400 Series Video Cards – Fixes the graphics bug that blocked players at the first snowmobile puzzle.
• Text Not Displaying on Non-English OS: Fixes issue that caused all in-game text to disappear if the game was running on an OS set to any language but English.

Rules Updates

• Two puzzles— Maw of Madness and Hydraulic Headache – had additional rules text added that clarifies the requirements of the puzzles.

Puzzle Updates

• Room Key Confusion: In the original version, the “NINE” text was much bigger and vertically-oriented. In this updated version it appears smaller, and is horizontal. The essence of the puzzle is still the same, but the changes make it more straightforward to figure out.
• Cut Your Losses: In the original version, the goal was to draw a line connecting all the players that intersected with every pane of glass. In the updated version, the goal is identical to the first football puzzle: Draw a line connecting all the players that avoids every pane of glass.
