Double XP Weekend is coming up, running from 12:00 UTC on 15th September until 12:00 UTC on 18th September. Hot on its heels is the next big batch of Invention content, and we wanted to let you know how the two will work together. The Invention update hits on 18th September, right after Double XP ends. Among other things, the update will bring brand-new blueprints. So: Have an amazing Double XP Weekend, guys, and we'll see you in game on the 18th for all the Invention you can handle.
