There was a live Q&A on facebook earlier today and it was said that the moon mirror would be offered on live worlds but they did not say when.There was talk of a building that boosted nut collection (or cheeses or moons.... whatever it is this time). Was that just a ruse, or something that was tested on Beta, but not brought forward?
I don't know if by saying you have no interest in the grand prizes you mean you will not be collecting them but if you amass enough moon splinters to get the prizes they will be given to you when the event finishes anyway. At least thats what happened to me in a previous event. I did not want the grand prizes so did not collect them but they were in my inventory at the end of the event.I've also decided this time around that I'm not interested in any of the grand prize buildings.
