Nostalrius Begins - Quality wow vanilla realm (1.12)

I started using realmplayers addon and I'm a contributor. I realized my data was ignored because my client thinks realm name is "Nostalrius Begins PVE" when it actually is "Nostalrius Begins PvE". (Note the small v)

Addon is using GetRealmName() api to get the realm name and it returns the wrong one.

In-game realm selection list has lowercase v, but once I select it, in character list page, top right shows it with uppercase v.

I used the official installer for client. Does anyone know if these strings are stored somewhere in game files?

This isn't really a server issue, you may have to contact the creators of the Addon, or leave a bug report with the creators.

Or consult a FAQ on that addon, maybe there is a setting you can change.
Also you can ask in the addons section of Nostalrius forums, there might be someone else using it.

This has nothing to do with addon, it is client's mistake. addon is just asking what realm name is, and client is returning wrong value

Oh my apologies, I read your post wrong, I thought it said "My addon thinks realm name is Nostalrius Begins PVE"

Sorry.
