Up until the last update I really enjoyed playing but now there is a problem and it keeps throwing me out at the point where I should collect a reward for transport. I haven't been able to play for last 3 days. I am waiting for this problem to be solved very soon or I will stop playing. The problem in December was fixed but now the game keeps crashing again every time I try to collect a reward and I then lose all progress. Very frustrating! I am so close to uninstalling it.
