Poly Object Start Spot doesn't respect skill levels

I can create a poly object with an anchor point, then put different start spots down and flag them for different difficulties and coop and multiplayer and whatnot. None of that seems to matter, the poly object goes to the same spot regardless of the game mode.

They are not supposed to. Polyobjects are not actors, they are part of the map defined through thing entries, these are not skill filtered, just like any other controller type thing that is being used to modify the map on load.
