Hi, the loader belt stacking option of this mod is removed if SA not enabled. However, belt stacking could work without SA enabled (I mean own DLC, but SA disabled. Not sure what will happen if not own DLC).
I am playing PY which is incompatible with SA but supports belt stacking. So, adding the option back greatly helps. This would be very very useful for PY and any other future overhaul mods which are highly likely incompatible with SA.
