Issue description: All items in my grid are gone, despite the card showing it is full of items, 23,401 to be exact.

What happens: Accidentally put my full inventory into the storage grid, when I reopened it i cant see any items, JEI crafting still works, it shows you don't have the ingredients but they appear when you click the auto-grab item button.

What you expected to happen: The mod creator might see this and be able to fix it for further iterations.

Steps to reproduce:

1.I'm using a 256k storage disk from "Extra Storage" so compatibility might be an issue, but I'm playing the Direwolf20 pack on FTB. I accidentally put my "Portable Grid" into my storage system, when I reopened it I cant see any items.
2. I was able to use 1k storage disk and the "Disk Manipulator" to get the item that caused this glitch alone onto a 1k storage disk and the only item I don't have anymore is my "Portable Storage Grid" and the disk it's stored on only shows 1 item, and you cant see the item when you open it.
3.I have access to every item that was on my 256k card due to moving the grid to a different card, but have lost access to every item currently stored in the "Portable Grid."

4:TRUE REPRODUCE::: Put "Portable Grid" into current "Storage Grid" (this did work with 1k disks) then close the grid, when reopened nothing will appear to be in the grid, despite the card having items.

So I think you meant to say: "Grid appears empty when inserting a portable grid into it."

I can't reproduce that. Having multiple versions of mods should not be a problem, but I've heard rumors that the feature that picks the latest version may be a bit buggy, so I would not recommend doing so.

There are other addons in the pack that might also be interfering here and plenty of user error possibilities. As such... please come back if you can reproduce this with just RS.
