Yea.... about that. I was told by ASDF that it isn't apart of the city and is made by Gecko for the Kiwike games so my only question is: did you get permission for floating staircases to heaven and the tower that is about twice as large as is allowed? As far as I can tell, Yotta hasn't "ok"ed these absurd structures.
Personally, if it wasn't oked, they should be torn down. A retrospect ok only shows an affinity for allowing such spontaneous actions that seek approval in hindsight when permissions should be sought prior. I'm all for these Kiwike games, but that doesn't exempt people from the rules and if it does, then it shouldn't be outside of a city.
