Quote from BlizzardPatch 31.2.1 is a server-side patch rolling out now with the following bug fixes and updates:
[Hearthstone] Fixed a bug where either player getting a Libram of Divinity to 0 mana caused animations to play slowly.
[Hearthstone] Fixed a bug where spells' internal cost reduction effects didn't work with other mana cost related cards when drawn via a Spellburst effect. (For example, Sunsapper Lynessa not doubling a 1-cost Holy Glowsticks after it was drawn by Ethereal Oracle).
[Battlegrounds] Fixed a bug where Golden Tea Master Theotar didn't provide buffs after his first sip of tea. He will be returned to the minion pool after this patch has fully rolled out.
[Battlegrounds] Fixed a bug where a Rerolled Hero could be offered to another player in the lobby.
[Battlegrounds] Fixed a bug where Moonsteel Juggernaut's end of turn effect didn't improve between triggers when triggered twice by Drakkari Enchanter.
[Battlegrounds Duos] Fixed a bug where a player could be offered Cho or Gall when the other half is in the locked Heroes for their partner.
[Twist] Banned the Warcraft Rumble cards (Warsong Grunt, Footman, Night Elf Huntress, and Gnomelia, S.A.F.E. Pilot) from this Twist season. They didn't do anything wrong, they just aren't supposed to be part of the Wonders card pool.
