ActionScript 3.0 :: Flash Hittest Only Works On Last Object In Array

For days now I have been trying to get this hit test to work and which ever way I try it, it always comes back to the same result. I get a hit on the last item I pushed into my array but none on the previous items I pushed in. Also if I put a .sort() on the array it only gives a hit on the last item of the array, no matter which one I push in.

The idea is that I want to drag and drop objects onto the stage, they may not overlap so I need a hit test on the objects so I can make them undroppable when the hit test is true.

This is the part I have for dragging the objects to the stage, and adding them to arrays for the hit test.

Code:
private function onClickDragBuilding1ToGameField(e:MouseEvent):void{
building1Placeholder.x = mouseX-25;
building1Placeholder.y = mouseY-25;

[Code]...

Now if I run this I can add the object to the stage just fine no errors or other issues but the hit test only works on the last object I added to the stage/array and not the previous object I added to the stage/array.

Sso I drag the first object to the stage. (no other object are available yet so nothing happens, this is as it should be) Then I drag a second object to the stage, this reacts to the first object and returns the hit test as true. (Also great and working as it should.) Then I drag a 3th object to the stage, this reacts to the 2nd object I dragged just fine and return a true value, but it does not react to the 1 object I dragged onto the stage. Then when I drag a 4th object to the stage it will react to the 3th object I added, but not the 1st ad 2nd object.
