have both Sinister Squashling pet and Hallowed Helm in my bag with my roll priest in WOW2 asian. However, the Sinister Calling Achievement cannot sucessfully achieved. I suppose the probelm may because I cannot learn the pet with my priest, as another role has already learnt and added the pet into my collection. However, it’s not reasonable that only one role could get the achievement. Please kindly check. Thanks!
