Japan at your fingertips, over 600 cars to collect, and now the live-service Series updates rolling out every week, you could easily spend hundreds of hours in Forza Horizon 6. In fact, many people already have. I’ve put in 50 hours so far, and plan for many more learning to actually beat Touge races in style for a change. But what if you could lose it all in the blink of an eye? Well, you can. Sorry.

A bug has been discovered that’s been wiping players’ saves pretty indiscriminately. Take a quick look at the various Forza Reddit pages right now and you’ll see a swathe of people hit with a blank slate.

“I’m genuinely devastated and there’s truly nothing I can do about it but hope it doesn’t happen again. I’m sick. Millions of credits, fully tuned cars, custom garage I built myself. F this game,” one player wrote.

Unfortunately, the official cause (or more likely, causes) is yet to be determined. While Xbox players are reporting having their progress deleted when using the Quick Resume feature, the same can’t be said for PC, where issues with cloud saves on the Xbox App and the game crashing have seen saves wiped. Another theory is that a handful of cars may even be causing data loss if you paint or upgrade them, including:

• 2003 Ford F-150 SVT Lightning
• 1993 Schuppan 962CR
• 1957 Chevrolet Bel Air
• 1994 Ferrari F355 Berlinetta
• 1988 Lamborghini Countach LP5000QV
• 2019 Porsche #70 Motorsport 945
• 2017 Ford M-Sport Fiesta RS
• 2020 Wuling Sunshine S Forza Edition (annoyingly, one of the best cars for drag racing)

You’re not guaranteed to run into issues encountering any of the potential causes, but frankly, I’m not going to chance it. For the time being, I recommend avoiding these vehicles. Plus, if you’re on console, definitely switch off Quick Resume. PC players, either on Steam or the Xbox App, make sure to back up your save periodically—it should be located in C:\XboxGames\GameSaves/pgs. Just copy the file to a safe location, in case you need it.

If you’re unlucky enough to get hit by the reset switch and can’t recover your save, you should contact Forza Support, where you can get your inventory—cars, money, Wheel Spins—restored, but you’ll still have to retread the campaign, find collectibles, and that sort of thing.
