My goal for this challenge was to get all 3 sirens and a Fire Fly and maybe a Cupid troll. I was one of the unfortunate that was kicked out of the game for 24 hours. I gave up on the Armored Siren and focused on the Fire Fly. I used every piece of energy I had, all my crates I had saved and still was not enough. I had to use some gems and used the siren statue that S8 gifted me for my troubles and sped her a bunch of times and got the Fire Fly. I think they should have gifted me all the energy I would have accumulated while it was down.
