This report applies to trunk r9671.

Often, I'd like to build a nuclear plant or another building somewhere, but there's a tree or rock in the way and it needs to be harvested or blown up first.  In this case, it would be convenient if I could queue up orders to an engineer so that he first harvests the tree and then builds the nuke plant in its place.  However, that seems currently impossible because the game won't let me place the second order while the tree is still there.
