Inventory lagging

When the inventory has many craftable items on the bench (and other stations of creations) the inventory is very stuck and is almost impossible to create some item.                                             This happens when inventory is full of items that can be used to make other items such as stone, stick and etc.                                                                                                                                       But this makes the inventory of the workbench become very stuck and almost impossible to make any item, such as blocks, weapons and etc.
