So a few days earlier I had 2master balls in my backpack, but since yesterday I've noticed that they're gone and I'm 100% sure that I haven't used them in catching pokes, I even checked all the recent pokes I've caught and no master ball icons, and I haven't started the Heatran quest, nor the Pinkan Island quest (in fact I've already finished it). *Update* 10h later i open my back pack to see that my rare candies are also missing, had 160+ now 11, and some other items.
