runtime error: Cannot read 0.hidestat
Why are mobs becoming 0 and how can I fix this?

Maybe you can show us your code so we know what's going on?

UpdateState(value, max_value)
                    if(usr.hidestat && !usr.stathid)
                            for(var/atom/X in usr.client.player_gui)
                                X.invisibility=0
                            usr.stathid=1
                        else if(usr.stathid && !usr.hidestat)
                            for(var/atom/X in usr.client.player_gui)
                                X.invisibility=0
                            usr.stathid=0

usr is not some automagical reference to whatever player mob.
It's use is only valid in input events, and almost nowhere else.

What is UpdateState() defined under?

obj
    gui
        hud
            New(client/C)
                if(!C) return
                else if(ismob(C))
                    var/mob/M = C
                    C = M.client
                if(istype(C, /client))
                    C.screen += src

            statbar_background

            statbars
                layer = 20

                var
                    num_states

                proc
                    UpdateState(value, max_value)

This is usr abuse plain and simple. You'll want to define an owner under the statbars or call UpdateState() with an arg of the owning mob.
