The following issues have been addressed in the 4.0.1a minor patch:
  • Using a "/cast!<pet ability>" command no longer disconnects players.
  • Mousing over objects that generate a cogwheel should no longer cause the client to freeze or disconnect.
  • Guild Tabards should no longer display on characters not actually wearing the Guild Tabard
  • Floating combat text should always appear.
  • NPC Health Bars/Nameplates are now appearing correctly.
