When I changed my nickname in WoW from RU:Козлодиор to Факинщит, I founded that my WoWLogs score aren’t updated even if I uploaded logs via “upload a log” function in your application(Uploader) or “live a log”.
There is my page on Wlogs https://www.warcraftlogs.com/character/id/33568059
Nickname on Wlogs: Kauris
