I was watching ads as usual for the daily gems and when I clicked to watch the next one it said something like "no videos are available" and the chest disappeared. I thought maybe I had clicked the button too fast after the last ad and it would come back after a restart. It's been 3 days and it still hasn't come back, and I haven't had the option to watch ads to speed up the event either. I've had issues in the past with ads disappearing that were fixed by changing my DNS, but that isn't working this time and I still have ads available on another runaway game.
Does anyone know anything else I can try to get them back?
