During the material- losing bug, and subsequent rollback, from a few weeks ago, I kept an eye on my 4300 silver. Nothing affected my silver during that time, though I did lose around 100 raid banners that never came back to me... (Not my complaint here). I have only played a couple of times since then, and I cannot remember purchasing anything for 600 silver, but I logged in last night after this recent rollback to find I have 3700 silver. If Bungie is reading this, is there a way for you to look at my store purchases and let me know if something was purchased? If so and I did make a purchase that I cannot remember, that is fine, but if not, I would like to be recompensed, if the bug-loss was the issue...
