The October 2013 Hacking was an event that took place from October 23, 2013 to October 30, 2013 when BZPower was hacked again. It resulted in every post from August 24, 2013 to October 23, 2013 being deleted, setting the entire site back two months and deleting two entire games in the process.
- Bionicle Mafia VII: Frozen Wastelands
- The only one of the three games to have been posted before the deletion window; however, the game had not officially started yet by August 24, and when the forums returned the decision was made to end the game.
- Mafia III-4: The Four Tribes
- The only game to both begin and end within the deletion window; the memory of the game was saved through a Google cache temporarily and through the logging of information on this wiki, but what several players believed to be one of the greatest ending scenes of all time was lost forever.
- Bionicle Mafia: The Ruins of Mata-Nui
- The only game started right before the end of the deletion window; the game was still in the process of deciding on the first lynching, and thanks to the wiki could be easily recovered and restarted. However, that never happened, and the game was not continued.
