I did top up 350 golds in US server close-beta test to join in 3x gold reward event. Then now I am playing in S1-Sarbe SEA server. I saw in google play, Snail games said that you only need to send email to supportusa@Snailgame.net to say which server you are playing now, then they will transfer all rewards to this account in this server. I did send 2 times to firstname.lastname@example.org, but received nothing.
