Just tried on EU,NA and Vanilla , appears to be working as intended.

 

You should only see names that starts with “the” right? You see other names now as well that has no match at all like “macdoctor”.

Ive used it a lot before 1.9.10, but after that update it was giving totally unrelated names back

 

The what you worded it I got impression you meant it does not create a list of names
