With Arma 3 there is this new stance system that allow a player to adjust the posture of a player character, however when a character performs a jump the posture/stance is not retained. This is mighty annoying, because I do not want to see my player character keep moving around with a hunched back, nor do I want to keep readjusting my stance to counter the game behaviour.

This type of problem is perhaps linked to any other gameplay feature in Arma 3 where the game does not retain information for the simplest things (retaining the set firing mode on a weapon instead of having the firing mode keep being reset to default value).
