A lot of RustBuster Players got banned by RustBuster Client 1.4.6 with the message: "RustBuster Detected Hacks. Found an unknown hack. 7801"
This is a false positive. It is recommended to unban these Players manually (via /rbunban) or to wipe the banlist (The ini file, and do /unbanall and a restart). A Client update (1.4.7) is available.
