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.
Chaos in the midst of chaos isn't funny, but chaos in the midst of order is. - Steve Martin
