KCLT Mesh Issue
At KCLT, at the northwest corner of terminal E in the area of gates E32 - E38, there is a severe dip in the terrain mesh. To troubleshoot this I removed all addons from MSFS and the area was flat. I reinstalled my addons one-by-one and this dip didn't reappear until after I installed Real Taxiways.
If you let Just Flight support know they should be able to look into it.
