And, when I try spawn unit's in via the editor, they don't actually show up where I placed them, they don't show up at all is there any way (sure there is) of changing this?.
Something in the DayZ code prevent them from showing up in game - I don't know what file exactly.
If you want more units, you will have to spawn them via a trigger or a script of your own.
