Sometimes pets are assigned to a class, and the icons for that class shows blue/yellow as if buffs are missing, even though buffs are not missing on any player character. "show pets" is checked, Version 1.44
Opening buff assignments then shows the pets under that class as if they were a player

also warlock pets are shown, even though you can't buff them

This is intended. Pets will share Greater Blessings with their respective class since the Zul'Aman patch. The pets should also show up as their own flyout buttons for that class.

hm, okay, but it still behaves weird, sometimes the class icon is showing that buffs are missing even though everyone is in range and all players are buffed, and PP does nothing when klicking the class icon

Is this happening in combat or out of combat? There's a known issue with players being moved around in combat that I haven't gotten around to finding a good fix for.

Regarding in combat I will observe next raid (thursday) specifically, Definitelly out of combat.

never experienced the described issue, is this still in observation?

I regularly experience weirdness with pets and PP, but not like this thread anymore, this can be closed, if I can identify a specific issue I will open another one.
