Are the dedicated server files you linked to able to be used with clients whom have the Steam version of the game. I read on the game's web page that the files on those pages we not compatible. I looked on Steam and could not find a dedicated server package for Rising World. Digging on the web showed me that the server files for the Steam dedicated version should be number# 339010 https://steamdb.info/search/?a=app&q=rising+world however, those files do nothing when called with the steamcmd parameter.
./steamcmd.sh +login anonymous +force_install_dir /servers/risingworld +app_update 339010 validate +quit
The above does nothing and fails to find game.
To recap, is the link: download.rising-world.net/download.php?type=server compatible with the Steam version of the game?
