MY flag has gone since i ve changed my password.(i mean the flags on the right),help,how i can get my flag back??

it'll return in about 3 days or so, all you have to do is wait

Hey, I've moved your thread to the correct forum section. You are more likely to get help there.
Many people are experiencing this issue with the flag missing. One thing you can do is ask an admin to set your country code, but that is a temporary fix.

This issue is on our side, unfortunately we can't fix it until a higher dev shows up

I thought if you edited your settings, via Signature, or avatar, or location it set your flag for you, or does this occurrence bypass that as well

It's not going to work.
For now some ips won't have a flag in game but we're working to fix it
