The World of Warcraft's devs never seem to run out of woes with regards to the game's latest instance, the Sunwell Plateau.

Over at the game's Europe forums, Blizzard community moderator Thundgot is sending word that they've found "a pretty obnoxious bug" for the instance's Eredar Twins boss battle (Yes - it's them again).

This bug was making the fight  against the two far more difficult than it should be, much like the issue that was recently plaguing the U.S.' test realms. Thundgot notes that until they find a way to address the bug, the PTR's Sunwell instance will be temporarily closed.

You're probably wondering what the bug is, given that even Thundgot was calling it "obnoxious." According to player Compo, it appears that the Twins were generating random amounts of damage that caused the party members to die. That is, despite them group having 14 healers.

If the issue really is that serious, we do hope the devs get to the bottom of this matter. Drop by again in case we receive any updates regarding this bug.
