I've just bought another plot of land adjacent to my existing plot, and a Linden tree right on the corner is infringing into my property and it is not part of my design requirement.
The co-ordinates are Hector 153,23 and its a Eucalyptus tree.
I've also got a few pieces of undergrowth on my plot (around 155, 9) - Disco Inferno - that refused to go home when I sent all the other clutter home.
This is the third plot of land that I have had, and had the same problem.... perhaps you could look at why they aren't being auto-returned when everything else is, and save us the bother of reporting it next time?
Thanks
