Mistake with the Final 4
Throughout the tournament you notice fighters wore yellow belts and red belts. Nobody with the same colors fought eachother.
Dux and Paco had yellow belts while Chuan Ip and Chong Li wore red belts.
Therefore, the semi finals should have been Dux vs Ip and Paco vs Chong Li OR Dux vs Chong Li and Paco vs Ip.
