Name player loss after logging out from profile

Hello! We have RANKED server CONVEX, and yesterday i found that after login from another computer, i loss game player name. Then today i login to the game from computer in my office, and i see that my game player name become "Player", not INIT...

p.s. i have LINUX system in my home and office

*Its should be better if player has WARSOW account, and if he login with account, name player will be automaticaly state to his LOGIN name :) if player hasnt account and playing without login to account, he will be choise player nick

Separating login credentials and in-game nickname was a conscious decision we took, due to not wanting to enforce new habits for our old playerbase who are used to custom ingame nicknames.
Also those ingame nicknames are stored locally on your computer, they do not transfer from one computer to another.
