Blizzard have shared a known bug with Ouro in AQ40, and issued a warning to Hardcore players to not attempt the boss. Said bug can actually spawn a second copy of the boss during the encounter, and would very likely cost all the raiders their character’s lives!
Known Issues (Source)
Greetings,
The known issues post above was just updated with two new issues relating to Ouro in the Temple of Ahn’Qiraj. We wanted to highlight specifically here to raise awareness of these issues for groups on Hardcore realms attempting this boss. One of these bugs has a very high liklihood to cause a raid wipe.
Ouro may sometimes fail to re-engage the raid after a wipe.
Ouro may spawn an additional copy of himself after coming out of a submerge phase.
Developer’s Note: We strongly advise not attempting Ouro on hardcore realms until this is resolved as this is likely a guaranteed wipe if this occurs. We hope to be able to identify a fix for this very soon.
