The Rita themeing has basically stayed the same, it's just thgat everything is now covered in these like roots of the tree and stuff. So, that "Control" was there before, it's just now been like sprayed with faeces and had roots put all over it [:)]

actually, it has been slightly changed, if you look, previously it said "race control" in a slightly different text and postion. But the idea of the themeing, I think, is that Rita has been taken over by this thing, whatever it is. So the Rita themeing is the same, only covered in poop.
