Brett, I do not agree with your statement (but I am willing to be proved wrong). Considering there is only 1 definite beach cleanup, I am sure that I have had builders who have developed all their skills only after this puzzle has been completed.

I think what those posts are trying to say, is that if you finish all the puzzles offering building experience, the only way at present to gain more building experience, is to wait for another beach cleanup or two
