Although we made Artifact Classic and Artifact Foundry free alongside our announcements about those games last week and put them both on the same store page, the button to install or play Artifact Foundry didn't work (it incorrectly installed or launched Classic).

This has been remedied and now anyone should be able to install either or both versions, and a final patch for Artifact Foundry has been released.
