As to how and why the game gets stuck at various times. Equally frustrating is that when it gets stuck it might be a few days or a few weeks. I'm done reloading the game since doing so, doesn't fix the problem but it does cause me to lose boosters and other accumulated game achievements. I sure wish KING would put forth the necessary effort to review the technical to find and FIX the problem behind this "glitch". I am an avid user who's business I'm certain KING would like to keep as such. I look forward to a positive outcome.
