I lost more than half my backpack... INCLUDING ITEMS I UNLOCKED MYSELF (KGB, not sure what else...as in I deleted the original one I got and had an additional one in its place)
Lost my stovepipe hat too... god damnit.
Really isn't cool, can't they just say "Stop idling now, or you'll pay the price" instead of doing possible damage like this?
Don't really care since I still have most of my unlocks, but I had unlocked everything through achievements and lost a couple items and dupes and now don't have the items in question, period...
