I completed this Mystery before finishing all steps. It appears that you do not need to upgrade to v3 to achieve this.
It triggered when flying from Recreation to the Nightguard Tower, north-side flying by the lightning posts. Wingsuit was v2, before getting either of the Gravitron Repulsors.22:23, 18 May 2020 (UTC)
So just working on the mystery, the map included is accurate. V1 isn't on the map (NE corner of the recreation island) and then the area labeled for V1 is actually part of the V2 upgrade. The squares could also be a bit smaller. If anyone has some time to fix that, it would be neato. TheGreyFencer (talk) 20:40, 19 May 2020 (UTC)
