[ul]I can reproduce it pretty easily. Here’s what I do:
[list type=decimal]
[li]pick up batteries so that you wield them[/li]
[li]press d[/li]
[li]press left[/li]
[li]type in ‘10000’[/li]
[li]press right to confirm the number[/li]
[li]press enter to drop[/li]
[li]see how many batteries you dropped[/li]
[/list][/ul]
Now if you look in the inventory you have a ‘battery’ with no number by it, this battery is the “debt” I was talking about and if you drop it on the other batteries, you will have the same number of batteries as before you dropped them.
