I went to click on Colosseum ticket and got instead Arm Lock. Each of four different dialog boxes did not let me reverse this. Why not make all those different boxes, one box with the ability to reverse an erroneous craft? Same with dialog boxes stopping you from getting out of current brawl and into one that you actually want before it disappears? The dialog boxes take a long time to load and interfere with enjoyment of the game, sometimes very much so. When you are saving up for a card you want and set back horribly by a wrong click sparked by how slowly the list scrolls, it is very frustrating.
Love the game,
