As the title says I’ve just installed omaa for the first time (version 1.0.1), it’s great only issue is missing control tower. All other buildings are present. 

Hi there!

Please try reinstalling the scenery as well as clearing your scenery indexes!

To do that locate your folder by following the path below.

(MS Store) \AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalCache\SceneryIndexes

(Steam) \AppData\Roaming\Microsoft Flight Simulator\SceneryIndexes

Then delete the contents inside but leave the folder intact. This should solve the issue.

 

Thank you!
