Hello Infinite Flight Community!
With the recent 20.1 update there has been an issue in which many VORs have gone missing, however, I have discovered a solution!
Step 1:Find the 3 letter code of the VOR that you want to add. For example the Lambourne VOR-DME is LAM
Step 2: In the search bar of the map type vor [insert vor code]. For example type vor lam if you want to add the Lambourne VOR
Step 3: Select “Add to Flight Plan [Insert VOR Code]”
Then you finally have the VOR that was missing on the interactive map in your flightplan!
