Hi Devs! Before the update 1.82. the sound of track-collision, when tracked vehicle of player hit the small stone fences (which are abound at every step on the islands of Arma) worked perfectly.
It was a great feeling, when the tank with player onboard was facing an obstacle in its path, but now, after 1.82 this sound has disappeared.

I made a video example - https://www.youtube.com/watch?v=zJ_faAWSDbQ&feature=youtu.be
You can hear it - here are no any sounds, as if the player is riding a butter.

Unfortunatelly the absence of sound simulation looks very bad, when playing in the first person. The player has no more sensation that he is riding through the stones. BIS please return this collision sound back!
