A dedicated post on the official Forza Horizon support website aims to assist players who have been affected by this, and as of last night at 11pm PT, it's been updated with confirmation that a new Xbox system update is being rolled out.
Here's a bit of what it says:
"The XBOX team is actively developing platform updates for XBOX Series X|S and PC to help improve these issues, so please ensure your devices are up to date. On Windows PC platforms, these fixes have already been rolled out via the Gaming Services client. For players on XBOX Series X|S consoles, we are planning to release a system update that is targeting a rollout starting tomorrow, June 12. You will be able to proactively receive the update by following the steps outlined in this XBOX Support article."
As mentioned, those who are particularly concerned about this issue and want to address it ASAP can manually activate the update (when it goes live) by following these instructions:
- Make sure that your console is connected to the internet, and then press the Xbox button to open the guide.
- Select Profile & system> Settings > System > Updates.
- Under Updates, you'll see:
- Console update available. Select this to begin your update, or
- No console update available. This means your console is up to date.
Fingers crossed this will mark the end — or at least, a significant reduction in reports — for the Forza Horizon 6 saving issue on Xbox consoles, which probably only affects up to 5% of all players anyway.
It's not great that it exists in the first place, but they're clearly working hard to eliminate it as much as possible!
