Describe the bug

Put more than one item on the depot. The fireproofing proccess will output item. The number of items that were send out each time is as the same as the number you put originally.

For example, you get 8 iron ingot. You put them on the deposit. Then the fireproofing proccess will take 1 and give you 8 ingots back for each time. So you will get 64 iron ingot at last.

To Reproduce

1. Prepare some solution for fireproofing.
2. Get some item that can be pile up. We counted the number of it as N.
3. Put them on the depoit.

Expected Behavior

Each time, it will cost you 1 item and give you N items back.
