Buon Giorno,
So I thought I had all my issues resolved yesterday. I have the latest Addon Manager with 5 sceneries. I was doing a flight from DFW to ORD. In 2-D some of the runway/taxiway markings at DFW were missing. Everything was fine in 3-D and outside views. Landing at ORD, the terminals were missing, but the jetways were there. Upon restarting FSX everything at ORD was fine.
Any idea what might be causing that?
