I'm running into a repeated bug where when you pass the centerline in a bomber turret the mouse control pops back even if you have it disabled. The turret stays put and the mouse starts moving then the mouse disappears and the turret snaps back. Mostly noticed it when facing straight forward on a number of bombers, but recorded it in the B-29 and B-26 just for example.

There's also a VERY annoying bug on the B-29 waist turrets that snaps you backwards once you hit a certain sweet spot forward-down. It's very repeatable and happens in both F1 and F3. Very annoying.
See here:
Note the last F3 snap was it happening again, I wasn't messing with view angles or anything.
