I noticed that when I add different in size AtlasSprites to a layer, the positioning of the AtlasSprites isn't correct.
So if you have AtlasSprites with a size of 13x13 (width,height) and AtlasSprites with a size of 26x26 there is a remarkable difference in positioning the (x,y) on a layer.
So my question is:
"Why do the AtlasSprites have a positioning difference when the size of the AtlasSprites is not the same, and what is the best way to deal with this situation".
For people who do not see my challenge/problem there is an graphical explanation of the situation on the weblink:
