Griefing
On the 6th of November, 2016, the Exploit of Late 2016 was used by ChromeCrusher to reveal the location of Fitlantis. This allowed a group of random people to travel to the base and accordingly grief it. During this time, a battle occurred between the random people who showed up to grief the base and Team Aurora. On April 21, 2017, Fitlantis was destroyed by lavacasts and flooding.
