Hey, finally there's a fix for the speedplugin!
It's fixing the tac preventing or picking up equipment from a far distance.

Here's the code(used @hillbilly 's offsets)

Code:
using System;
using System.Runtime.InteropServices;
using Addon;
using System.Net;

namespace ReadyUP

    public class Class1 : CPlugin
    {
        string cur_version = "";

        int g_speed_var = 0;
        float jump_height_var = 0;
        int fall_damage_var = 0;
        int gravity_var = 0;
        bool fall_damage_enabled = true;

        IntPtr g_speed, jump_height, fallmax, fallmin, g_gravity;

                string[] downloads = download.Split(',');

                cur_version = downloads[0];

}

using the default speed/jh/gravity/falldmg in OnServerLoad and change it in OnMapChange fixed it.
you can use the default sv_config for this.

oldy post i know, but having a little issue including different speed/jump height for each map, i added it like my other one but didn't work, as i'm already using OnMapChange for the maps/speed etc
