All 5 Hidden Rainbow Event Currency - Days of Color Sky Children of the Light nastymold 

It hasn't worked for me in three days. The devs are incompetent, at this point I think their only goal is to waste peoples time.

@@asog I found that if you just go home and come back it will reset the things and you can try again. Only thing with that is that when it gets to the later colours you're gonna have to wait a long time just for it not to work.

People just can't seem to cooperate in a game about player cooperation... At least it's nothing serious.
