Thanks to the community feedback, the development team found an issue in the configuration of the World Map preventing players from playing the 2 new maps introduced in Season 2 (Forge & Temple Garden).
We are fixing this misconfiguration server side (with no downtime!) at 1:30PM EDT and it will take about 5 minutes to complete. Here's a handy countdown to this update for those not sure about time zones! https://www.timeanddate.com/countdown/launch?iso=20170517T1330&p0=165&msg=For+Honor%3A+Seamless+Maintenance&font=cursive
Any new login after 1:35pm will receive the update immediately. For those currently in-game, the update will apply at the end of the current turn of the Faction War! Note that the current turn will end at 2:30PM EDT.
