INVISIBLE BUILDING CRASHES

I have searched the forums for entries on invisible building crashes (IBC) but have found little, yet I know people elsewhere are experiencing these. I am experiencing the ICB at 4 addon airports Malta (Daniel Chircop); Incheon (Yunjin Lee); Johannesburg (Johan van Wyk); and lately at Castlegar (Vern Opperman). An example of an IBC when an aircraft moving or stationary, is on the apron near the terminal, a building crash occurs, particularly if in spot view when panning, and there has been no visible contact with the building.I had extensive messaging with Daniel Chircop but he could not duplicate any IBC
