I tamed King Bangalash and was unable to rename the pet from “Cat”. I tried stabling, logging out, and waited a day but no luck. So, I abandoned that cat and tamed another King Bangalash, but it had the same bug. I tamed a turtle and was able to name it. I tamed an orange tiger and was able to rename it. But, I tamed Bhag’thera and had the bug with that cat too. Maybe it’s just the named mobs, but I don’t see other players having this problem.
Edit: Okay this is weird, but I tried naming my Bhag’Thera “Scout” over and over and it never worked, but I named it some keyboard spam like “sakjhakjh” and it did work. Is this a problem with the profanity filter? I’ll catch King B and try a different name.
