This problem is still going on. Since it occurs randomly it's difficult for anyone to get screen shots of the questions. One morning you will get correct rewards, next not, and for three days everything will be fine...|
some of the questions also seem bugged or incorrect: "Which weighs more, one pound of lead or one pound of feathers?"
A: Tricky Question B: One pound of lead
the answer (as worded) should be, Tricky Question. It's one pound of anything... the weight is the same, one pound.
