Still having problems with World of Warcraft's boss Lady Vashj in Serpentshrine Cavern? Well, don't worry because Blizzard has already admitted that the encounter, and the whole cavern for that matter, is quite buggy.

In fact, several hot fixes have already been implemented before. Speaking of which, Blizzard Lead Encounter Designer Daelo dropped by WoW's official community forum and informed players that a new hot fix concerning visibility is now up.

Aside from the Coilfang Strider spawning rather weirdly, players have also reported frame rate issues in Serpentshrine Cavern. Daelo explained,

A change to the visibility rules for many of the creatures there has been made. Players will no longer be able to see many of the creatures at a completely unlimited distance, but at the more normal visibility range you typically experience with outdoor content.
