Now, I don't know what's up... I have gotten too many crystals, however sometimes something that isn't moongrass makes a poof noise in my pack. This wasn't whatever that is. I was standing in the house putting the crystals in their bags. Suddenly the last blue in my pack just disappeared. I'm in a house in tram so no one stole it. I guess it doesn't matter, but this isn't the first time I didn't have as many when I got home as I got. This time I just happened to see it disappear.
