why dont you get sure what you are talking about. There in no bug or any hacking.
Noone was screved because of any hacking!
A month or 2 ago when was last testing few people hacked and made them self free gems. Everything in game was reset today so they did not make any progress just waste their time. Well actually they did show what was needed to be fixed. That is what there are soft launches and testings.
Why the massive dump then?
Because google is probably going to delist the game from Play Store because they committed fraud?
And without multiplayer the game becomes pointless way too fast anyway. Crap launch.
