Weren’t you trying to restore a character with the name Subjectzero? That name was in use on Darrowmere as I mentioned before. It was someone else’s account, not yours.
I imagine it is the same situation, someone else is using the character name. Which is not considered a bug.
It is a limitation of the system that you aren’t automatically flagged for a rename if it’s been over 30 days, which is why we recommend that you contact Support in these situations.
Edit: I see the confusion. The Game Master who answered your ticket indicated there wasn’t a character of that name on that realm. There was, when I looked. It is likely something happened to the character.
