i just did the money glitch provided in the sticky, but i did it with every object so you wouldn't have to
I think what happens is: you have one of everything tucked away and you just build a map from scratch while still being able to spawn it right there and deleting as long as the original is tucked away in the corner. So you just go about your map, if an original item is in the way, you pick it up move it but don't delete it. After the map is done, you delete all of the original items. You could also just move the item but I am the same as you, I like to spawn it right where it goes. Hope that helps. I thought the same thing. If someone would so kindly do it for all maps, it would be pretty sweet.
no, this does not in any way trump the standard items limit. you will still only be able to spawn 24 double boxes, 16 pallets, etc.
