I had to reinstall my Ftb recently due to a crashing issue. When all was done and danny, I loaded my FTB set my controlls to the way I like. Now, when I use alt and button 1 to place one item from the item im holding into my inventory/crafting table etc. It just placed the item stack into my inventory, and sends one to the first open hotbar space. I had this issue with FTb before, i managed to fix it. any way to do this?
