I have the same issue. abandoned my pet today, but i still can summon it. it's twice the size than it was before. it doesnt use any abilities it once had. i havent any pettabs neither in Char windows nor in spellbook. the "pet" is controllable via attack, stay, to me commands. Can anyone help???

The bug is gone thanx to one of the Nostalrius's GMs. He offered me to select my bugged pet, open the chat window and run this command: /script PetAbandon("name of the pet") Hope anyone who accidently gets this bug will have no worries how to fix it by him/her-self.
