Shralock Pack spawn
 

Recently the mob that drops the Shralock pack has not spawned - myself, and friends have killed 20+ place holders and continued to kill the place holders without the mob spawning. We are starting to think it is bugged.

It's not. Every spider on the south wall of the zone is a PH - people just kill that static spawn because they can sit there AFK. He's probably spawned off another spider and is roaming around.
