If you insert an item into a crafter block at a certain time, the item will disappear.

In the situation where I discovered it, I put crafter blocks facing each other, disabled 8 places on one side and put 1 stack of iron ingots in it, and placed 9 stacks of iron nuggets in all squares without disabling any of the other blocks, and iron nuggets. If you press the shift key and left click on a certain crafter block at a certain timing, about 9 stacks of iron nuggets will disappear.
