Guild Wars 2

And once you finish the event it ends the fire ele event chain… is this new or have I gone a year and a half without knowing this could happen?

What do you mean? If you mean the C.L.E.A.N. 5000, it goes through the reactor plant during the fire elemental pre-event, then during the fire elemental event it gets wrecked and appears back at Rooba’s camp again after that.

Been there since beta. He was much worse (but oh so fun) then now.

That is just the result of failing the pre-event.

Fire Elemental pre-event: Defend the C.L.E.A.N. 5000 golem = http://wiki.guildwars2.com/wiki/Defend_the_C.L.E.A.N._5000_golem
upon failure: Destroy the C.L.E.A.N. 5000 golem stolen by the Inquest = http://wiki.guildwars2.com/wiki/Destroy_the_C.L.E.A.N._5000_golem_stolen_by_the_Inquest
which is followed by: Destroy the chaotic materials created by the reactor meltdown = http://wiki.guildwars2.com/wiki/Destroy_the_chaotic_materials_created_by_the_reactor_meltdown
So I’m guessing the evil CLEAN 5000 just wanders around until killed? (because destroying the chaotic material is the pre-pre-event – the one right before defending the CLEAN 5000)
