Neverwinter exited open beta last week for its official launch complete with the new Gauntlgrym update. Gauntlgrym added a new PvE mixed PvP dungeon to the MMORPG, but a few serious issues turned up last week that prompted Cryptic to temporarily disable the dungeon.
The short version Â some characters on Dragon shard running Gauntlgrym found their characters locked to the location and were unable to log back in or change locations. A recent update addressed server-wide disconnects for the dungeon but work continues on the other issues.
