When you first launched AI MiG-21 in DCSW, the aircraft would get protective cover over closed canopy and ladder after the shouting down of the engine at the parking. But after the last update and the release of the DCS MiG-21bis add-on, my AI MiG-21s are parked with open canopy and without ladder. Why? I found the ladder (and possible cone and jet exhaust protective covers like in Flaming Cliffs) to be very neat, cool and realistic. Can you return the ladder, at least?
