I guess, it's because of some kind of cache issue, causing some people to start from the 1st level over and over again earlier. Now your weakness has become your strength)
I played for ages coz i was going for the hard badge but i ended up needing 11 more blue chests in 10 weeks which is impossible so i was like screw this game
it glitched and the game completely froze except i could go on inventory and i kept getting level ups and i could spend skill points it was pretty awesome
