If your pets are dissapering when using Call STABLE Pet "spell" (5 min CD) after logging in/out or disconecting, try using the Stable Master NPC and draging your remainig active pet to any of the slots available and then use Call Pet spell from BM spellbook tab, it should bring back 1 by 1 each pet that you lost by using the bugged spell Call Stable Pet. It worked for me after a log in/out. Hope that it helps.
