Hello, My bug with the event (since the start of the event) is that the quest don't validate itself, it stay at 0/2. I could kill as many dragon and other mobs in the event area (during the event time i'm not stupid) as i could it change nothing and there's no reward, no loot/drop... I have free place in my currency bag…
Found 3 eggs (aproximately 50 box opened), 4 crown (what's the use of this crown ? what to do with it please?), a lot of potions lvl 60, 30 000 AD, 20 residuum and 5 cristals (blue). found only box on monster with power equal of saber spider or more. If your lvl 60 you can farm mobs lvl 54+.
