I can not summon my guild page Herold Pet. i Have even go so far at to try an re purchase them through the guild vendor. No joy.
i have noticed a few other posts like this, but no fixes are listed
It is still not possible to summon either of these almost 3 years later. If they are no longer available to players, they should be removed from the vendor.
i just tested the Guild Herald pet. it summoned without issue. it does have a cooldown of 4h before you can summon it again
