I'm not sure how many airports, or areas are affected by this 'conflict' 'glitch' (or whatever word you wish to use)
It's across various versions of P3d (not sure about V5)
Here's just one example I've found:
Load a GA aircraft at CYXX - (GATE 2 - GATE SMALL):
Man in overalls, with a spanner who walks backwards a few steps then comes forward, kneels and adjusts something. (see photo)
After you load Devil's Tower:
Man in overalls is STATIC,...but the spanner moves on it's own (see photo)
It's easily recreated - Use Central to uninstall - run P3d @ cyxx gate 2 QUIT.
Then install Devil's Tower - run P3d @ cyxx gate 2
As I said "Don't know what (or where) is affected"
