I noticed that if your game crashed RIGHT when you receive loot... The loot doesn't go into your inventory BUT you get the annoying gold dot indicator that you have a new item.
Obviously when you go in and the dot shows you have a new helmet and you actually don't, there's nothing you can do to get rid of the dot. This happened to two of my heroes already.
Please fix these kind of minor bug by just coding defensively. There should never be these kind of race condition where the "new item indicator" is flipped but the item didn't appear. Use transactional logic so these kind of thing won't happen (so either you get no loot, no indicator OR you get loot and indicator, not one without the other).
