I have had the ODDEST problem... Ever since the recent patch, I've had annoyingly wicked NOSE BOUNCE, on every plane!
I know it's not anything I did because the night before I was kicking arse and having fun, flew for many hours, then the patch comes out and the day after I was flying well (all the memories sitll fresh in my head) I now cannot use rudder without bouncing ot hell and back, and just lining up a shot is a pain in the arse.
