yeah that would be the best! its annoying to try to fix that1 Pivot is used for sampling randomizations. It must be in the same position if You want the same transformation as Your neighboring objects.
I suggest that IToo puts a check point for that, and better, a check point for every object in the group to control which one I need to be independent and which do not, hopefully in the next update.
The problem could derive from the Forest Pack object considering the pivot of every object independently in scattering, ignoring the group's pivot.
Adding 8 ver. to each object in the group is to much work....:/Sorry, then. I hope You will get away without using Translation transform.
