Maybe this help. I have same problem wih Esplanade on Mac and Safari yesterday and Clear cache and Resting Safari browser dont work. Than I Delete All cache in Flash Preference pane (100Mb for Tanki) and after again load few games, all works as before.

Map is not ready for public. :( In 30 minute playing on various server, every Silence game have a hacker. User jobbb, mister_krutoi, lluJloTka... I have a few shots as proof.
