Found a bug in a clean script. Until I update this asset you can manually fix this by replacing htme_clean_signed_packets with this:

/// @description  htme_clean_signed_packets(client_ip_port);
/// @param client_ip_port
function htme_clean_signed_packets(argument0) {
    /*
    **  Description:
    **      PRIVATE "METHOD" OF obj_htme! That means this script MUST be called with obj_htme!
    **
    **      Cleans the players signed packet buffers and ds maps
    **  
    **  Usage:
    **      ip:port     string      ip:port combination as stored as key in the player map.
    **                              or "" to clean all
    **
    **  Arguments:
    **      <none>
    **
    **  Returns:
    **      <nothing>
    **
