Update 21.3.3 Release Notes

[Screemer]

Here are the Release Notes for 21.3.3, released on Wednesday, January 31st.

News and Notes:

The game launcher will no longer crash when the game is down for an update. The launcher will now show a dialog letting you know the game is down, and then open the launcher so you can view the newsfeed. It will remain "Stuck on Installing Pre-Reqs", but it is not actually installing prereqs. NOTE: This behavior will begin after the game is patched to 21.3.3.
The cosmetic shield Fingar's Lost Scale has a chance to drop when defeating Fingar in Challenge difficulty of the Abyss of Mordath raid.
An Osgiliath travel mount, with automatically-granted war-steed Caparison and Saddle appearances, has been added to the Gorgoroth Steel-bound Lootboxes, and the Ash of Gorgoroth vendor. The mount skill-granting item can be freely traded.
There is a new set of item level 340 earrings in the raid Abyss of Mordath and Gorgoroth Steel-bound Lootboxes. These Spring-themed rings have a new cosmetic effect, and can be found in Sagrog's loot. The names are Earring of Spring's Arrival, Earring of Spring's Promise, and Earring of Spring's Rite.
A Lasgalen Owl cosmetic pet can now be found in the Gorgoroth Steel-bound Lootbox.
Some crafted Doomfold Instance and Raid gear will no longer incorrectly claim to be Bound to Account instead of Bound to Character on Equip.
The Abyss of Mordath first boss Challenge requirements have been adjusted to match the Challenge quest description.
