The reason for the two "Mina Dos Estrellas" episodes was because the entire group of contestants did not complete their dares. This was the only time fewer than two contestants managed to finish all the dares. The "Mina Dos Estrellas Part 1" episode was the only episode where every team member quit. The investigation was later completed by another group of investigators in Part 2. The "Two Stars Mine" (which is "Mina Dos Estrellas" in Spanish) in Tlalpujahua, where the episode was filmed, was the actual site of the deaths of 400 people as a result of a massive flood. This is also one of the only episodes of the series in which most of what the cast is told is historically correct.
