The pet will get auto stabled regardless of stable limits.Kyronix, will there be any problems with your pet being auto-stabled as sometimes happens when your character dies if the character's stable slots were over-filled from previously using the mastery for boarding purposes, but it was not active when your character died? In other words, if the character had not died at that point and instead had gone to the stable, he would not have been able to stable the pet(s) he currently had out without activating the mastery.
