Empowered Wings Reset in Naxxramas for Season of Discovery (SoD)
Blizzard recently put out a hotfix that was aimed at correcting some issues with the weekly reset of the Naxxramas raid, and one side effect of this fix is that player-selected difficulties have now been reset.
With that being the case, you should check to be sure that you have the correct wings empowered before you begin your next raid.

At 12:12 p.m. PST today, we deployed a hotfix to address some issues preventing Naxxramas from reinitializing properly after a soft reset.
This hotfix cleared player-selected difficulties. Before raiding Naxxramas, you’ll want to reselect your difficulties manually and interact with the Burning Conduit as you would when entering a fresh raid for the first time after a lockout.
Thank you!
