Damaged Tower and Boulders.

I don't recall any rule stating otherwise. Also, it would put a harsh score ceiling if you couldn't go beyond a certain number of points in the tower.

(In the event that you didn't find where in the manual it says this, try checking under 3.3 Scoring, specifically around Penalty Assessment, where it says
