I was playing the mission "Dusk" in the Deployment campaign, sniping from just outside of the enemy's range like usual when I experienced a sudden loss of control, my aircraft bobbing and weaving like crazy and trying its best to spin me in circles. At the time I had auto hover and turn to target on so I turned both off and tried to regain control. I was never able to get back to anything resembling normal flight.
I had had a few SAMs launched at me but I didn't think I had gotten hit (mission debriefing later confirmed this), and it wasn't like I was hovering too close to the ground and accidentally clipped a power line or something. Nothing worked like it should. Turning auto hover back on caused my aircraft to list backwards uncontrollably, like it was trying to loop. I ended up quitting the mission because I couldn't line up a shot.
And I realized just now that I should have saved the flight recording but I didn't. Any ideas what would cause something like this to happen? I'm not the greatest pilot in the world, but I can at least tell when something isn't working like it should.
