Hi,
please try following …
- close the sim
- be sure, that the Navigraph Navdata Center is still running in the background
- delete the
content.xml
file … you find the location here (depending of your MSFS version) - start the sim and try it again
In nearly 99.9% it´s a mess in your scenery file, which comes from the sim-updates. This procedure re-create your scenery file fully automatically again during the sim startup and after that the scenery entries should be located on the correct position.
Cheers,
Richard
