Forza Horizon 5 Update v1.671.650: Rune Part 1 - A New Adventure Unfolds

Rune Part 1: Unleashing New Challenges

: Added new vehicles and seasonal events to the Festival Playlist.

• Design: The rune challenges are well-integrated with FH5’s open world — they encourage exploration of lesser-traveled landmarks and reward varied car usage. Objectives favor precision (drift gates, careful boosts) over brute speed.
• Difficulty curve: Reasonable for casual players but offers room for mastery; a few poorly telegraphed checkpoint windows can feel fiddly.
• Replayability: Limited in this first part — once runes are found and objectives completed, there’s little emergent content beyond chasing best times or alternative car runs.
• Progression value: Rewards are cosmetic-forward and light on game-changing content; good for collectors but not for players seeking significant new cars or gameplay systems.

1. The Grey Texture Glitch: Certain player-created decals would render as flat grey squares on the 2020 Nissan GT-R Nismo.
2. Wheel Support: Logitech G923 users reported a loss of TrueForce feedback after 15 minutes of play. A hard restart was required.
3. The Rune UI Bug: When viewing the "Car Mastery" tree for the Ford F-150 Raptor R, a phantom "Rune" icon would appear in the bottom left corner. Clicking it did nothing (this was the hidden placeholder for Part 2's skill tree).

Players are encouraged to ensure their game client is updated to the latest version to maintain compatibility with online Horizon Life sessions and the latest Festival Playlist rewards.

Let’s break down everything solid we know about this update, from byte-level fixes to the mysterious "Rune" designation.
