I have been using Ghost's new PTG, and I have been generating large pieces of terrain using it. The issue is that since the generated bricks are floating, bricks I place on them can't be removed by a hammer. Dwanding these bricks breaks all of the connected bricks. There does not seem to be a ground filling option for the new PTG, unlike the old one on RTB (unless I completely missed it). Is there a way to place and destroy bricks on a floating brick as if it were a grounded brick?
