I used to love this game but now it keeps crashing between loading screens. It means I can only do some of the free challenges, some of the time and I'm fed up paying extra gems to do a challenge that should be free, only to see the game lock up again, losing my gems. I was nearly kicked out of my clan because the game froze every time I tried to play the clan battle. I've sent off messages from the support page but I have had no replies. This problem seems to be affecting lots of people...
