Hey both,
i hope this message finds you well.
I have just installed the Iceland demo and I have the same issue.
I have Global Base, Europe Open LC and Vectors. I ran AEC and applied the changes. I checked if I had a another airport afcad and I didn't.
I also have BIKF from MK Studios. Terrain is fine there. Could it come from this scene? I haven't tried uninstalling it to be honest. Hopefully I don't have to.
Thanks a lot,
Take care,
Pierre.
