Here is a saving/loading code that I'm using for a game of mine. It works perfectly except for that you don't appear in the place where you last savd your game. No clue why.

verb
Load_Char()
var/savefile/F = new(ckey)
Read(F)
usr << "Character loaded."
Save_Char()
var/savefile/F = new(ckey)
Write(F)
usr << "Character saved."

Make sure your saving src.x, src.y, and src.z, do this:
Make:
var/lastx = src.x
var/lasty = src.y
var/lastz = src.z
save those variables
load to those variables
at the end of the loading code
type:
src.loc = locate(lastx,lasty,lastz)

How would I do that?

Here's an example(This is what I use).

        SaveChar(char_name)
            var/savefile/F = new("/[src.ckey]/[char_name]/Player.sav")
            var/lastx = src.x
            var/lasty = src.y
            var/lastz = src.z
            F["LastX"] << lastx
            F["LastY"] << lasty
            F["LastZ"] << lastz
            F["Inventory"] << src.contents
            F["Mob"] << src.client.mob
        LoadChar(char_name)
            var/savefile/F = new("/[src.ckey]/[char_name]/Player.sav")
            var/lastx
            var/lasty
            var/lastz
            F["LastX"] >> lastx
            F["LastY"] >> lasty
            F["LastZ"] >> lastz
            F["Inventory"] >> src.contents
            F["Mob"] >> src.client.mob

You used
F["Mob"] >> src.client.mob

What's wrong with this? Well, you, as the mob, are pointning to the client, who is pointing straight back at the mob. Instead, use
F["Mob"] >> src

Also, You don't need "Inventory" since mob/list/contents gets saved along with the above line anyway.

Hope this helps :)

Now working at all now. Here is my code.

SaveChar()
var/savefile/F = new("/[src.ckey]/[char_name]/Player.sav")
var/lastx = src.x
var/lasty = src.y
var/lastz = src.z
F["LastX"] << lastx
F["LastY"] << lasty
F["LastZ"] << lastz
F["Mob"] << src.client.mob
LoadChar()
var/savefile/F = new("/[src.ckey]/[char_name]/Player.sav")
var/lastx
var/lasty
var/lastz
F["LastX"] >> lastx
F["LastY"] >> lasty
F["LastZ"] >> lastz
F["Mob"] >> src
src.loc = locate(lastx,lasty,lastz)

If you mean it DOESNT work, it's because you have to do all that stuff in Write and Read then call them..

mob
    verb
        Load_Char()
            var/savefile/F = new(ckey)
            Read(F)
            usr << "Character loaded."
        Save_Char()
            var/savefile/F = new(ckey)
            Write(F)
            usr << "Character saved."
    Write()
        var/savefile/F = new("/[src.ckey]/[src.name]/Player.sav")
        var/lastx = src.x
        var/lasty = src.y
        var/lastz = src.z
        F["LastX"] << lastx
        F["LastY"] << lasty
        F["LastZ"] << lastz
        F["Mob"] << src
    Read()
        var/savefile/F = new("/[src.ckey]/[src.name]/Player.sav")
        var/lastx
        var/lasty
        var/lastz
        F["LastX"] >> lastx
        F["LastY"] >> lasty
        F["LastZ"] >> lastz
        F["Mob"] >> src
        src.loc = locate(lastx,lasty,lastz)

When I try to save with that, it gives me an error that keeps appearing and Dream Seeker does nothing but show the error, over and over again. It said that it couldn't read the savefile.

It can't read a savefile if it hasn't been written yet, is the savefile even there? '-_-

I know, it's really weird. But that's what the error said. And the savefile never appeared,
