[2.x/Space age], Since when are buildings demolished when trees are felled?

Space age , I realise that more and more extremely useful subtleties have been abolished/destroyed.

I'm dismantling trees and why, pray tell, are pipes being removed all at once?
If you cut down a tree first and stay on the button, NO buildings/pipes/belts should be demolished! That kills the flow of the game.
