Now, the problem. As I said above. Everything as I said above, everything is working as intended in frmDesigner. But when I load it in frmGame, it doesn't display it correctly at all. Everything is wrong. However, If I leave the grid size at default (16,11) the grid loads correctly but the items do not.

Is it because of these 2?
