Thanks for the answers. And sorry, my speak english not very good.
Problem not in gold. Problem in levels of characters (1-40 level). Since a certain moment, they don't raise in level. It has begun when I have bought Ezran, but I am not sure that the problem in it.
On end of the scenario, characters remain with... former level. At animation, destruction the monster cards, experience charge is also not shown. In Quest-mode not problem. All good.
I reinstalled a game, but it it hasn't helped. Unfortunately, I can't check on other device now. My login only through GameCenter, I don't have other device with IOS.
