I have been trying to get a key from the Mingler for the past three days. I have done more than 30 buildings and I have been to the factory atleast 3-5 times but I still have not recovered it. I am unable to get any other tasks till I finish this one. I took friends who had the same task to 4-5 story sell bot buildings and they got it the first time they tried. Why am I the only person having this problem, its so frustrating that I'm thinking about leaving the game. I have spent countless hours on this toon and I really don't want to give up. Can someone tell me what the problem is? What am I doing wrong?
