This event was the most difficult for me so far to find event boxes at the start. I was lucky to find one, and then for four hours or more, nothing at all. Even with supercharged energy recovery! I ended up staying up late and hitting all the high XP targets I could just so I could level up, and with the energy and stamina refills was finally able to start getting some briefcases. Anyone else have difficulty getting started with this event?
Having meow collected ten briefcases though, I'm really hoping I don't encounter that problem again.
Oh, and for those of you who opened this thread thinking I already won the end prize, psyche! Start paying attention to the difference between an event box and an event currency!
