Hello, I am currently trying to tame new pets to teach my boar new levels of bite and charge. He is currently loyalty 6, and I rather like his model so I am attempting to do it by stabling the pet I want, and taming a new one like you normally would. However, even with a slot purchased at the Stable masters, I cannot put my current pet into the stable to be able to tame another. Is this feature bugged or disabled on this server, or is there a way for me to get it to work? Thank you
