Ok i was there and here is how it happened!! Troy was on the left lane bowler on the right lane had left a 4,7. Troy thought he was through bowling and reset the spare off the lane for his 12th shot. After realizing the mistake called the desk for a respot of the spare. somehow the mechanic went to respot the spare on the wrong lane. It's not the firsttime that has ever happened and i can guarantee it won't be the last time it ever happens.
