Issue description:

Some disks are being emptied too far. For example, I have a 64k storage disk with "Stored: -103/64000"
.

And sometimes Interfaces become clogged with 0-item stacks (literally, red number saying 0 ).

What you expected to happen:

Well, not that.

Steps to reproduce:

Difficult to say, but EIO and IC2 machines both make the 0-item stacks (in fact, EIO made some -100 stacks, which could be picked up repeatedly as full item stacks, so something is very wrong there - integer overflow on stack sizes?)

Version (Make sure you are on the latest version before reporting):

• Minecraft: 1.10.2
• Forge: 12.18.3.2185
• Refined Storage: 1.2.17

(DireWolf20 1.10 pack v1.4.1)

Does this issue occur on a server? yes

No crashing, fortunately.

The disk issue is a duplicate of #520 and the 0 stack issue is caused by an external mod inserting invalid stacks in the inventory? I don't see how that is an RS issue.

Except that the 0 stacks are coming from both IC2 and EnderIO. Which have nothing in common, that I'm aware of, and this doesn't happen with items being inserted into any other mod.

RS doesn't transform stacks into 0-size stacks, something is inserting an invalid stack into the RS inventory.
