Talk:Mystery Crates/@comment-5303258-20120829073338

My sister and I both got the 21 crystals without completing the mission. We clicked through the mission and then on the mystery crate and cancel, mystery crate and cancel 5 times. We had to do that, from the start, 5 times. Then tipped one person and it gave us the 11 crystals. Then we repeated that and got the 10 crystals. It only takes a few minutes to do this. It took maybe 20 minutes for my crystals to show up.
