The question How can I leave a dungeon/instance? uses the tag archlord2. I figured that since all our other tags have a hyphen between the name and the number, this one should too. So I tried renaming it to archlord-2, but got this error:
You are attempting to create the tag [archlord-2]; however the tag [archlord2] already exists! If you think this new tag should be allowed, raise it on meta
I do think that this new tag should be allowed, and the old one should be deleted without a synonym. Can someone who has the ability to do this make it happen?
