Hello! Welcome to our forum!
That folder contains the beta navigation data (AIRAC) we provide for MSFS2024.
It is not meant to override any scenery, but we have several open topics dedicated to issues that show up when this package is installed, so I am not entirely surprised. The core issue seems to be that Asobo has changed how the order of packages is being kept internally, which means that we can no longer manage this ourselves. This appears to be causing issues compared to MSFS2020, where we would manually control the order.
We have yet to find a foolproof solution despite following the guidelines provided by Asobo. Feel free to give these instructions a go, though, to see if they help your situation!
Apologies for the inconvenience! We’re still working on this, trying to figure out what’s going on.
Kind Regards,
Malte
