Nostalrius Begins - Quality wow vanilla realm (1.12)

my level 40 priest zeres is missing from my logon.. what can be done?

Nothing, they don't restore characters.

Do you have multiple accounts? Ensure the charcter is in your account. Go into the account name folder you are signing into to check for the character name you are missing.

WTD folder>Account folder>(Account name) folder>Nostalrius begins folder> here are the character names associated with that account.

i only have one account. Is this some kind of bug? to log on and have a character missing? this does not make me so hopeful for any character i level and put work into. are we only allowed a certain amount of characters?

Whatever the character limitations were at the time of 1.12.1 vanilla is likely what they are here on Nostalrius. Staff doesn't delete characters nor do they restore deleted characters for whatever reason (Accident, compromised (Hackers), etc.).
