Bubble Confusion...

Apparently two players busted at the same time before Daniel Neilson's exit hand, going out 171st and 172nd. But because the Neilson hand caused so much interest, after they counted the remaining players they found there was only 169 players remained (including Neilson).

Therefore if you busted just before the bubble, then head back to the Rio and you might be splitting 171st place money!
