Clarification on the questions:
1) I blow up the foundation of a house with nothing left supporting the top part, but it just floats in mid air. How to make it fall without needing another rocket?
2) I blow up a wall, bricks go flying, some are loosened. But after a while, the loosened bricks and the debris reappear at where they were before I blasted the wall. How to stop this from happening?
I'm using the demo version.
