BeforIn the the 1.64 update, for three years, I never seen such was added bug.
If the stone is in front of the player and this player want to lie on the ground, nowthen, he can not do it.
In this case, all you will get - is a look into heaven in a not natural body position. Probably was the idea, to create the effect of obstacles for weapons, but the result is turned out, very bad. The collision model, does not fully match the size of the stone. At a distance of 1 meter weapon collides with an invisible barrier. As the human body is the position of the snake:

https://feedback.bistudio.com/T117123 - This bug was added in the update 1.60 and was ignored in last updates - 1.62 and 1.64! How In Arma 3 the player must escape from a fire? If he automatically stands up, when crawling and if he cannot prone before the shelter. Such shameful errors are critical for the game, because this all can annoy players. I hope, this all, must be urgently fixed in the next update - 1.66www.youtube.com/watch?v=Sgt8IYEfeVM&feature=youtu.be
