Hi, I have a super neighbour who has the big tools for 6 hours.
I asked if she could re-arrange dogwood trees on 1 farm of mine.
She did. She moved a lot of dogwood trees to another spot on the same farm.
After the work was done we both reloaded that farm and poof all the dogwood trees were again at their old place. The super neighbour has all the rights on that particular farm. She restarted the move and after loading the farm again the trees were again at their old place.
What have we done wrong? Or what should be done to move the trees and keep them on their new spot?
Thanks in advance for any advice.
