Back to rating. I lost coins this last event because I never got the rewards for the last event. It just restarted. I feel that your events are overwriting the "collect rewards" screen and deleting them. Until it's fixed, I'll readjust my review. BTW, this isn't the first time it happened to me. This time was the only time I lost coins. It kind of sucks because events are the surefire way for extra coins too.
