Nostalrius Begins - Quality wow vanilla realm (1.12)

tldr:

1) new to Nostralrius
2) Leveled up for a bit.
3) Reached level 3.
4) Logged out for the night.

Today noticed there was 5 realms. 3 of them says Dev Only. And the other 2 is Nostalrius & isVV.
After noticing isVV does not say Dev Only click to see what is there & get disconnected.
How to go back to Nostalrius? Was 100% not cheating! Can't select correct realm is the problem.
How to fix?

in the realmlist.wtf add a line under the first line :
set realmname "Nostalrius Begins"

that should work

I get the same problem, wanted to check what it was and now i cant log in.

I have this issue aswell and I can't edit the realmlist.wtf folder
