I just deleted one of my characters to create a new with the same name but it says "That name is unavailable" is this some kind of a bug or something needs to be to use the name. I red in some old topic that server restart fixes this and want to ask if this is the case when is the next planed server restart coming if someone knows of course.
that bug is common on Wotlk core and as you have already read on those old Threads you need to wait a server restart/crash
If you are facing the same issue on TBC core most likely it get fixed the same way as Wotlk care, wait server crash/restart. ( weird is the first time I read about this on TBC core)
I guess there is not planned restart soon, so you need to wait for a server crash
