FARL - it deletes everything it lays. What am I doing wrong

[FlashBangWallop]

I cant seem to "suss out" why it deletes everything behind it
Ive loaded blueprints and they were accepted - I can run FARL anywhere I want - but it deletes everything behind it.
I just cant work out where Ive gone wrong

You have bulldozer checked?

[FlashBangWallop]

Doh. I just assumed I needed that checked to bulldoze forests
Thanks
I literally couldnt see the wood for the trees

I could tell you that I originally thought the same thing, then figured out that that's what it was doing, but it would be embarrassing...
