When I use the Summon Pet feature, it shows I currently have four (of five) slots filled - with one being an Enthralled Gorm that doesn’t have an icon. In the Stable, it doesn’t show up at all.
I don’t recall taming one, and I would have thought its name would revert to its pet type ( Carapid) and not stick with the NPC name.
An unusual glitch and I can’t remove it from my list of active pets.
