Since I don't see any other thread for it, and there's no post on mmo-champion about it yet - there were several Hotfixes during maint last night that I've noticed so far.
Edit: Noticed a bug that was introduced so sorting list into intended and unintended.
Intended
- Loot Chests (CoT:Strat, Oculus, etc) now sparkle with loot sparkles.
- You may now loot Stone Keeper Shards if your faction controls Wintergrasp while it is in combat (previously nobody could loot them during the 40 minutes of battle)
- Archavon the Stonewatcher (10man atleast) now has a seven day reset instead of one day.
Unintended
- Titan Relic in Wintergrasp appears no longer to be interactable (Only confirmed for Horde on Ner'zhul and Horde on Frostwolf) this means that it is impossible to change which side is controlling wintergrasp.
