Here another similar glitch but this time it's WORSE than the original post of this thread which was my first posting here.
I pick an Escort mission and went to Cockpit and this. Maybe 10 RAH66, KA52, AH64, all on the same parking spot.
After I started the engine and took off, two KA52 and one AH64 took off from the same spot to join me in the Escort mission..
Then as we were flying away after finishing the Take Off flying around, I saw one RAH66 pop up into the air from that bunch, with its window open, rotors not turning, float in the air and then land on one of the parking spots nearby.
You can see from the next to last screens that there are 3 empty parking spots available. You can also see from the last screen I am flying away and there are still several choppers in that same spot.
