Issue description: I just wanted to submit this I know I've seen something similar to this in other bug reports but I'm going to submit this just because it's a bit different. I had started a refined storage setup and crafted a 64k storage disk. I was going to move all my items out of 12 large chests into the refined storage system using importers and half way through the transfer items stopped appearing on the grid.

What happens: Items stopped appearing in the grid during item transfer to refined storage.

What you expected to happen: Items to transfer from chests onto refined storage disks.

Steps to reproduce:

1. Have a controller, disk drive with 1k storage disk and 64k storage disk, pattern grid, crafting grid, and 3 crafters.
2. Connect importers to 12 double chests and start transferring items to refined storage.

• Forge: 1.12.2 - 14.23.4.2705
• Refined Storage: 1.5.34
