Merge Academy Miners game

Whenever I try to collect coins or energy won on the game board, the game will not save. No error is given, play continues, it just will not save from that point. When winning coins from completing tasks, it will save. It will save with all other game board play, just not with coins or energy. There is no way to win the pottery wheel. No prize was listed, or given, for completing 250 merges.
