This challenge was initially placed into Level X even though we actually had its solution. Thus, we changed its level to III. However, we now have moved it again - this time from Level III to Level II. Through discussion with the community we determined that this level better reflects its difficulty (as is the case with part 3). We apologize for the initial misjudgement and are sorry for the change in points, though we have made sure that no significant ranking changes occur from this.
