I was just going through the rank list for October cook-off and found this :
rank : 134 user: its_dark.
timings for solving as: 02:09:39(6) and -383968:00:00(0) and -383963
I could not find such errors elsewhere in the list but i think there is some definitely some problem with the rank and timing allotted to this user. @admin please check for other such anomalies and make the necessary corrections.
