Installed Megascenery Pacific Northwest on my system a while back. Noted that in addition to it taking forever to load, I have a very snow covered Seattle, and fireworks in the city of Seattle whenever I fly over it. That said I removed it. Now unless I am on a runway at KSEA, I am kicking up dirt with my tires. This occurs everywhere except, as mentioned the runways. Tried a couple different afcads, checked for duplicates, and found the only thing that will fix the "dirt" issue is to run the Megascenery PNW. Any ideas what may be going on or has happened to cause this? Thanks in advance.
