i never had a problem in development mode or stable mode.
Not sure what you mean. The NAV radio I set. Stuff like weather and weight (block) wouldn’t hAVE AN EFFECT on it turning out of managed mode, plus it doesn’t do it every thime., just about 80% of the time. As far as I knew I always had the bug since before experimental it wasn’t needed to put heading in managed mode.
It also happened before AI used EFB to program throttle, as well as after.
