Issue description:

Items inserted into storage system in any way will have weird numbers (often multiples of 8) and often cant be retrieved after inserting them.

What happens:

lets say I put 64 cobblestone in a crafting grid. The grid will say I have 8 cobblestone and the cobblestone cant be retrieved after.

What you expected to happen:

I expected to get 64 cobblestone on screen and be able to take 64 cobblestone back out.

Steps to reproduce:

1. build RS system.
2. Insert item.
3. close grid.
4. Re-enter grid and see your wacky numbers and vanished items.
