I have been playing Cityville from the past several days on my Facebook account. But now I have been struggling to full the Feed the Fans mission intended for at least a week. I wanted one indefinable soda ... been cropping more than a few Burger Joints frequent times for each day by way of no consequences. When I opened the quest again last night, I found that one of my sodas had vanished, as a result currently I require 2 over again. What can I do now? Should I give it up for now?
