We are continuing to investigate stability/crash issues reported by the community on Sim Update 3 flighting update 1.5.1.0. Please note these issues have not been resolved in 1.5.2.0 and will be addressed in a future Sim Update 3 flighting update.
We’re also investigating another top issue reported by the community (the sim only recognizes one connected peripheral), and working to fix this as soon as possible.
Thank you for your patience and feedback!

RELEASE NOTES Sim Update 3 Beta - 1.5.2.0
If you are playing on PC, outdated packages in your community folder may have an unexpected impact on the title’s performance and behavior.
If you suffer from stability issues or long loading times, move your community package(s) to another folder before relaunching the title.
FAQ
Will joining the Sim Update 3 Beta (and future Sim Update Betas) impact my progress in Career mode on the live build?
- No, Career mode progress is locked to the live build. No Career progress made in the flighting build will carry over to the live build. However, all Career mode specializations are unlocked by default in the flighting build.
Will my leaderboard records in Challenge League transfer when the flighting build becomes the live build?
- No, Challenge League leaderboards in the flighting build will always be separate from the live build.
Will progress in other game modes (Discovery, Free Flight, etc.) be separate in the flighting build and live build?
- No, only progress in Career and Challenge League are affected. This could change in the future.
Will content I own or purchase in the Marketplace be available on both the flighting build and the live build?
- Yes, all content owned or purchased in the live build or the flighting build will always be available in both builds.
