In the grand scheme of things there is no harm, no foul as far as the contestant and studio audience are concerned. No contestant was disadvantaged; on the contrary, the contestant was enriched by $30,000. They did absolutely the right thing in restarting the game and awarding the contestant the money even though it won't be seen on TV. And make no mistake, it could just as well have happened on Roger's watch, and you can be sure there was a meeting after the show involving the person responsible for making sure the monofilament is removed. The money will come out of the prize budget as if the contestant won the money on the air because it is the production company's responsibility to make sure the game was "unrigged". Problem is, they're over budget already.
Everybody take a tranc now.
