(See the best response by Albro1.)
Code:
        NewMob(mob/M, F as file)
            var/mob/Player/PC/NewMob
            var/mob/Oldmob = M.client.mob
            var/MobPath = "/mob/Player/[lowertext(F["Class"])]"
            NewMob = new MobPath()
            NewMob.Read(F)
            NewMob.loc=locate(NewMob.last_x,NewMob.last_y,NewMob.last_z)
            M.client.mob = NewMob
            del(Oldmob)


So i run this after logging in and it gives the error

runtime error: Cannot modify null.mob.
proc name: NewMob (/mob/proc/NewMob)
  source file: Procs.dm,36
  usr: the thunderz (/mob/new_player)
  src: the thunderz (/mob/new_player)
  call stack:
the thunderz (/mob/new_player): NewMob(the thunderz (/mob/new_player), savefiles/telnet/players/thund... (/savefile))
the thunderz (/mob/new_player): Login()

Why not just take client/C as an argument instead of mob/M?
NewMob(client/c, f)
    // bla bla
    c.mob = //bla bla


Just an idea to avoid any possible mob confusions going on here.

Hmm okay ill try it one minute.

okay it no longer is getting an error...but i must be creating the mob wrong or something ;/ mob/Player/Logout() isn't being called or something on logging out..

It works when first creating the character but if you login with that mob creation process and logout mob/Player/Logout() isn't called..

hmm
