Trees and bushes don't react properly to explosion shockwaves or wind

Trees and bushes don't react to explosion shockwaves beyond the initial blast. In other words, they "flinch" but snaps back alsmost instantly in static position and don't wiggle back and forth like in BF2042 and some other previous titles, some physics application seems to be missing (unless this is intended behaviour). Wind direction don't seem to affect the even smallest bushes and tiny plants.
