Issue description:

I had a little network in my base (Fluid grid + Grid + Controller + Disk drive) with 1 4K storage disk, and a 64k Fluid storage disk. And I just decided to change my base's location, so I took my drives in the disk drive, and moved. Then, I reinstalled the entire network, putted the disks back in, and opened the grid.

What happens:

The items didn't show up. I tough I did it wrong, but no. Note that If i add new items they show up and no issue with them. But all the old ones are totally out of reach. I even tried in creative mode to get the items out of this cell trough a disk manipulator, nothing. (Note that the items inserted after the bug occurs had been transferred, it only locks on the others.

What you expected to happen:

I expect the items stored in the disk to show up.

Steps to reproduce:

I don't know. It only happens a very few times.

Don't make duplicate issues if you know you're making a duplicate issue.

This is a Forge bug.

But I've worked around it in development versions. Coming soon.
