So when i went on multiplayer i just saw my flag is from Iceland instead of Romania and i was like What the actual fuck? I received an email with someone trying to enter my acc from Iceland but i didn't thought this will change my flag? What can i do?

nah dont panic. its just a glitch it always happen to me (Iceland, Norway, Sweden, UK, USA )
just try to re-login(esc>setup,>login>and reclick the "login")

Oh well silly bug...Solved. Thank you, closing this now.
