It happened the same to me in 2 different characters (2 troll hunters). Petbar got full but with only 3 pets actually aviables... Is Devilsaur the problem? 'Cause when I called it, it disappeared and gave me other call pet problems. My arena mate has got it, and when he uses Devilsaur's Buff (before the arena starts), it "dies" and after that it instantly gets up, but with all skills in cooldown as they were used (Rabid, Dash, Cower...). So I confirm the bug. Please fix it!
