My system has spontaneously developed a problem in which the terminals, runway markings, terrain, etc., have disappeared at four airports: KMEM, KCLT, KLAX, and KSDF. I have no idea what caused this. I don;t have the problem at other FSDreamteam airports (e.g., CYVR, KFLL, KJFK, or others). The problem is limited to the areas where the FSDreamtam product provides the autogen and terrain - if I slew the aircraft off the airport, everything is fine.
I've uninstalled and reinstalled each of them, and confirmed in the Addon Manager that they are installed and active. I don't get error messages of any kind.
Any suggestions on how to debug this will be appreciated. Thanks.
