Load(). You're creating an empty savefile (var/savefile/F = new()) and then trying to read from it...! It looks like you've just copied your Save() procedure and just reversed the >>/<< signs and replaced Export with Import. That's not going to do it.

What you probably meant to do was set F to new(src.client.Import()) instead of just new(). That will get the player's imported savefile.

There's another problem as well: The way you're trying to load the x, y, and z vars. You need to actually load the values into the vars themselves, not just src:

F["x"]>>src.x
F["y"]>>src.y
F["z"]>>src.z


Even that won't always work, because if src is at null then it will just stay there; setting x, y, and z independently won't work in this case. The best solution is to load the values into temporary vars and then set the coordinates all at once by using locate(), like this:

var/X
var/Y
var/Z
F["x"]>>X
F["y"]>>Y
F["z"]>>Z
src.loc = locate(X, Y, Z)
