I used to have 6 characters on test server, honestly I didn't need them all and I didn't use them all, but some of the ones that I did actually use are no longer showing up in the character selection screen for some reason.
Update, even deleting one of the remaining characters to make room, I can't even create new characters.
Might have something to do with my issue. I just got started on the Test Server, however I couldn't access due to a character of another faction already being assigned to the server. The problem being I just got the Test Server and hadn't even made a character yet so there's definitely something wrong with character recognition.
