Ok,
This is what I have to say about these,
I have 5 quest outstanding - 4 of them need something done where I would have to spend farm cash for a facility or tool(one of them need 2), which I don't have. So, now I can't do any except 1. And those 4 do not expire for 4+ days.......
I am not about to spend loads of farm cash to get some coins once a quest is complete -- I already have 800 million coins
Otherwise the few that I have done are ok.....
