Forza Horizon 4 Bug Wipes Some Players’ Car Mastery Progress

Forza Horizon 4 Bug Wipes Some Players’ Car Mastery Progress

In Forza Horizon 4, vehicles are like characters in a role-playing game. Players can grind for skill points to buy perks and unlock each vehicle’s full potential. A game update that went live last week wiped many players’ skill trees clean, erasing months of progress. A fix is in the works, but the developers say it could take weeks to implement.

Reader Dennis tipped us off to the situation over the weekend, pointing us towards a massive thread about the issue over at the Forza Motorsports forums. According to several players’ accounts, the error occurred following the installation of the May 7 “Series 9” update for Forza Horizon 4.

Upon entering the game post-update, some players discovered that the car mastery perks they’d unlocked for their vehicles had been reset. Making matters worse, these players also said that perks purchased with skill points following the update would reset when they restarted the game, making further progress impossible.


This is very unpleasant news for the Forza Horizon 4 players who’ve been affected by the bug. The car mastery system, one of my favourite features of the game, is one of the most compelling reasons to play.

In order to unlock all of a single vehicle’s perks, players must spend hours driving that specific car, stringing together tricks to earn skill points. With more than 600 cars in the game, that’s a lot of driving. Understandably, the affected players sound upset.

The poster of the original forum post wrote, “After today’s update, I’ve lost almost all progress. It’s like I’d done nothing. Any light anyone can shed on this would be appreciated. I’m sick to my stomach right now.”

Developers reacted quickly to the issue. On May 8, the day following the bugged update, Forza Support Twitter acknowledged the problem. On May 10, a fix was issued that prevented the issue from affecting any more players and made it so that purchased perks did not disappear upon restarting the game.

What the fix did not do is restore skill points to the players who had lost progress. That particular fix is going to take much longer, possibly weeks. From the Forza Support Twitter:

  • We are now working on a fix to return all players’ lost Skill Points. We are expecting this fix to be live with or before the Series 10 update.

The Series 10 update for Forza Horizon 4 is slated for release in early June, so the fix for skill points could arrive any time between now and then. In the meantime, players affected by the issue have been awarded 10 Super Wheel Spins for their troubles.

Perhaps they can win cars via the in-game prize roulette to keep them occupied until their favourites are restored.


  • I got hit by this. Then I got hit by the game deleting itself when I tried to reset it after a glitch. Great game but deeply unstable.

  • Cant you just spend 15 mins drifting through fields with hills to get those skill points back? Or have they changed how that works? I confess i haven’t played it a lot recently, just jumped in for some drifting while deciding what else to play.

    • Nah, I’ve lost a good several dozen hours worth of skill point spending. I’m not even at a particularly elevated level, either – it just takes a good 15 minutes to fully upgrade a single Legendary car if you spend that drifting non-stop. This is quite disappointing.

  • The statement that “players must spend hours driving that specific car” is incorrect. You can earn skill points from any vehicle and allocate them to any other vehicle.
