I had never experienced this bug back when everybody was complaining about it, and honestly thought it had been solved. But it just caused my arena game to hang. As you can see in the screenshot, my action bar doesn't appear. I didn't take consecutive screenshots, but basically I can do everything except actually complete the battle. I remember there was a dev update that this had something to do with CHS, and there were (unconfirmed?) reports that thrawn caused problems, but as you can see, thrawn was already dead by the time this happened (and had been for a while) and CHS was obviously nowhere present.

This cost me a refresh, but your support team kindly reimbursed me those 50 crystals. So excellent job there, but I would prefer not to get bugged in the first place.
