I ran into it. Didn't say I continually used it, asked for anything for it, or explained how to use it. So yeah heads up. Sorry I don't know the official way to report a glitch. I guess I should be more of an expert with my 10 posts.
My game is loading on and off, They changed the gold for achievements, and game play is now extremely choppy all because they had to update the game to force people to spend more money.
