My host was given this error after a little while of hosting along with

the telefromvaihang (14,1,5) (/turf/tele/telefromvaihang): Enter(the cero (/obj/cero))
the cero (/obj/cero): Move(the telefromvaihang (14,1,5) (/turf/tele/telefromvaihang), 2)

Try replacing all the usr's with A or M(M after you defined it atleast). I'm pretty sure you should only use usr in verbs only. Also, the ismob(A) || if usr.race etc. thing is kind of strange. Because the usr is an object, it most likely doesn't have a race var. That could cause the problem. If the /obj/cero type doesn't have a race var, it would produce an error. Also, if you want them to all have the race var, give the atom/movable type(objects/mobs descend from them) the race var.
