I can see artefacts around the airport
If you can see odd artefacts around the scenery this is likely the result of a conflict with another package.
The most common case is that you have two scenery packages installed for the same airport. Please remove the one you don’t want to use from the folder.
Another common case is a conflict with the default X-Plane Gateway. This is a collection of plausible default locations made from ‘lego brick’ assets. All of our products are built to disable a gateway airport if present. If you are still having issues please contact one of our support agents.
