Your flag, your choice
Aksel asked for this and its done. In Options, under Display and interface, there is now a switch called Hide my country flag. Turn it on and the flag the game detects from your connection is gone from beside your name everywhere, and you also leave the "players from the same country" list.
Some of you don't want a real world flag next to a fantasy name, or simply don't want to tell everyone where you live, and I get it..
It hides only your real country. A flag you got in the game (Pirate Crew, Knights Order, the MagicDuel flag, a spell flag or one i set by hand) is not your country, so it stays shown whatever you pick. If you earned a pirate flag you keep wearing it :)
