Problem with particals

Hi
I rendered my video in render farm and after combining all pic together i`ve got this:

some rocks on background suddenly twist and began rotating in opposit direction about every 16 seconds.

In viewport everytning was fine and I thoght may be something happend during render.
Is there any way to make particals remeber their rotation and motion, bake it to keyframe, or something so it could render without such unexpactable twisting?

You can create a cache of your particle system (click on Bake):


Since you want to send your file to a render farm, do not use external cache…
