Code:
mob/player
    proc
        AutoSaver()
            set waitfor=0
            while(src)
                if(cansave)
                    var/savefile/F = new("Saves/[src.ckey].sav")
                    if(!tosenBalloon)
                        xco=x
                        yco=y
                        zco=z
                    F << src
                sleep(10)

Not sure why i'm getting this run-time error when i try to auto save the player, any help would be appreciated

edit:
Solved by Nadrew:
setting index value for mob like so: F["mob"]<<src instead of: F<<src solved the issue. recommended to delete file before saving as well as its possible for two identical indices to have different data.
