I have installed both files (ACG IWM Duxford FS9 + ACG IWM Duxford Airshow Addon) and I activated them in the indicated order:
When I take off from Duxford EGS2 at 12:00 GMT (13:00 Local) there is another scheduled flight of a Spitfire Mk XIX & a Harvard (Taz) taking off from Duxford EGSU. BUT only the Spitfire reaches that position. When the Harvard starts moving to follow the Spitfire lead, it wobbles & DiSAPPEARS!! Here is the static position of the Harvard, behind my Demoiselle:
Demoiselle & Spitfire taking off...
...but NO HARVARD any more!!
To make things a little stranger, when I try to fly in formation with the other Harvard (09:00 GMT or 10:00 Local) the very same thing happens: it starts getting in position, wobbles a bit & DiSAPPEARS!! Here is the Harvard schedule:
Is this situation correctable? HOW? This happens in my three FS 2004's: Golden Wings, Silver Wings & Ford Tri-Motor Tribute - and only whith both Harvards. All other Ai aircraft fly very well. GRACiAS
