Ive had a pet issue when ever i go onto uneven ground, like a pill of rocks that dip in and up real fast, my pet will get stuck in those rocks, sometimes is not just rocks, and will be sitting there butt stuck in the ground. its happens going up those spiral towers like the ones you would see in barrens, my pet's butt would get suck in the crack between the top shelf of the tower and the spiral path.
it really bothers me expecialy when im about to enter a fight with a mob. all of a sudden my tank is stuck head in the sky, butt in the ground. and i have to dismiss and summon really quick.
Pets always like to get stuck on certain things. Sometimes they will teleport next to you if its somewhere that you would have to like jump a gap to get to. But when there just stuck on ground i think there little AI brain is frying lol
