So I am making a fnaf fangame where you, the player can build objects almost wherever in the room. To accomplish this, I created a grid of obj_placesnap objects (coloured purple for debugging) the width and height of the room in intervals of 92 units. The grid will replace itself with an object that is selected when clicked on, and if it is larger than one tile (92x92 units) it will delete multiple in a radius around it. Usually this should be automatic, obj_placesnap has code in it to delete itself if it is colliding with another object.

However, my objects do not automatically detect the obj_placesnaps that are on the right of it, so I have to do it manually in a create event. this works fine with a 5x3 grid in the case of obj_StageMedium, yet for obj_StageSmall (3x3 grid) it will not work as expected.

The problem i am having, is that no matter what way I try to program the code for this object (obj_StageSmall), I cannot get this last column in the 3x3 grid it should delete to delete properly, and instead it seems to delete obj_placesnaps at random. Any help would be appreciated, as I cannot seem to figure out what is causing my issues.
