Probably not, but I have yet to see if drone death of this type effect your score. I know the normal loss of a drone counts as a death in the bomber catagory.
If your into scores, then yea, I think its a problem.
BTW, to me, the bug looks like the code gets into a staled flight condition, and doesn't know how to correct itself.
Since the drones don't break formation untill the gear goes down, and in this case I was already low and slow, with two notches of flaps, when the drones broke formation, they HAD to go into a stall while banking so hard, yes?
