I have been working a Gui for a block and I have 1 last bug that I cannot seem to resolve. Anyway the problem is that the result of my 2x2 crafting square results in the correct item but the item only appears every other time the 2x2 square is updated. I have a System.out statement in the onInventoryChanged() method. This seems to show that this method runs twice everytime an item is placed. Also when the 1st item is put into the 2x2 square the onInventoryChanged() method runs 4 time. This is the only bug in this code I know of.
