When my sugar drops are close to 180, if I collected too many in one level, the lottery screen will freeze for several minutes then go directly to "Level passed" screen. And I don't know what happens during that time.
For example, now I have 175 sugar drops. I collected 35 drops in one level. (175 + 35 > 180 + 24) After finishing that level, it stuck at 180 sugar drop lottery screen for a long time then nothing happens. Eight hours later, if I'm still playing, it will stuck at 24 sugar drop lottery screen again. During that time, I don't know whether I have got rewards or not.
It only appear at HTML5 version. I know in the Flash version if I collect too many sugar drops before 180, the next round will start from 23.
