its correct.
under wanted status, a plunderer might be atked by other players.
"If this player loses when challenged, he will not lose anything" -> other player attack u and he lose. he will not lost anything. u will also not lost anything.
"if he win, he will got some coins" -> you will lost your coins.
So if u are in wanted and you lost to someone, you should lost 50k coins and they gain 50k coins.
thats afaik hahaha no one atk me yet :p
