Season 4 Episode 3: Long Live The Lich is not available in the Gem Store for free, as the front page says. Even in the story journal it says it costs 200 Gems still.
But the front page of the Gem Store says it is available and it is free, yet when you click that, it takes you to the Upgrade section and there is nothing there. The free experience booster is available, but Long Live The Lich is not.
“If I had a world of my own, everything would be nonsense. Nothing would be what it is, because everything would be what it isn't. And contrary wise, what is, it wouldn't be. And what it wouldn't be, it would. You see?”
