I love this game, and the iOS version is great. Until you get "stuck." Multiple times Ive gone to play a card, I go to pay the resources, and it thinks I need more than what I really do. Whats worse, is I dont even have the resources it thinks I need, and you cant cancel. So youre just stuck. I tried leaving and coming back, but nothing. Then I kill the app, come back, and it tells me there was an error and it cant continue my game. When you put so much time into a game and its nearing the end, this is the worst. This usually happens during odd circumstances, like when youve lost a card due to a variety of circumstances. They just need to better think through the edge cases and it would be awesome. But its not worth starting a game when I fear it wont let me finish.
