Yo team—Forza Horizon 6 is an absolute monster of a game but there's one catch you need to hear right now before it eats your save file for lunch. Microsoft released a statement through IGN about an active investigation into lost saves and they have some specific advice that will keep your progress intact. The issue boils down to how Quick Resume works: it keeps the game resident in RAM so you can flip between apps instantly, but when memory gets tight background games are swapped out and their save states can get corrupted or dropped entirely — literally hours of tuning gone in a second. They don't have an immediate fix yet because they're still diagnosing the root cause which is happening across multiple Xbox titles this gen so proactive steps are non-negotiable for anyone investing real time into Horizon 6 right now.
The support team's direct recommendation is simple but crucial: disable Quick Resume specifically for Forza Horizon 6 through your console settings and don't let it keep the game suspended in a resumable state between sessions. Go to Settings -> System -> Saved Games & Apps and toggle off Quick Resume so your save writes fully each time you quit rather than leaving it in an unstable limbo that can get purged during memory pressure events. If you really want to keep Quick Resume enabled for other games, the safe alternative is to always launch FH6 from fresh instead of resuming — manually close the game and relaunch later so a clean state saves your data properly every single time. Either path works as long as you aren't relying on resume mode across app switches during intensive gameplay sessions which is exactly where this bug bites hardest for anyone switching between Horizon 6 and other titles they have open.
Here's some context that makes this less of a panic and more of a known quirk: Microsoft actually acknowledged similar save issues with Forza Horizon 4 back in the day and eventually patched it, so don't assume your game is permanently broken — the team just needs time to replicate the bug properly before they ship a fix. You can also add an extra layer of insurance by ensuring Xbox Cloud Save is active for your account because even if a local save gets nuked there's a decent chance a recent cloud copy will restore it quickly enough that you won't lose much progress at all. So disable Quick Resume as the primary defense, keep your cloud backups current as the safety net, and stop worrying about losing your car collection while everyone else is still building theirs.
