Moving trees already in the map

[Monolithic Man]

Sorry if this has been answered before.

I need to clear an area of map of trees. I'm certain I've done this before using the line:

(Object 172022) SetPos [(_Xco + (Random 30)), (_Yco + (Random 30)), _Zco]

But its been a while since I've scripted and it doesn't work anymore  
The line gives no errors but also doesnt move the tree at all. I can change the direction of the tree alright and destroy it but I cant move it  :-\

Any ideas?

Thanks in advance.

AFAIK you can't move preplaced objects.

Live with it or set your scene on a different part of the map.

DO like this!

Create some gamelogic on the map, name it "place"

Then create some triger,
Condition: True
ONACTIVATION : (object xxxxxxx) setpos getpos place

xxxxxx - the number of object

you can "object ID setpos[1,1,-100] "in 1.75 and 1.75- but in 1.91+ you can't do this.
