Asobo Studios und Microsoft haben einen Patch für den Microsoft Flight Simulator veröffentlicht. Dieser soll diverse Fehler an Sim Update 9 beheben. Im MSFS-Forum gibt es zum Update eine Release-Note:

If you are playing on PC, some packages in your community folder may not have been updated and, as a result, may have an unexpected impact on the title’s performance and behaviour.
Please move your community package(s) to another folder before relaunching the title if you suffer from stability issues or long loading times.

General bugfix 1.25.9.0

Unfortunately, 4 weeks of beta testing (with two build updates) did not help us clearly identify some crashes related to operations on the world map when downloading packages or content in the background that have been released alongside Sim Update 9 (1.25.7.0). We are working to identify this gap in our beta testing and aim to better cover these cases moving forward. We thank you for your patience.
