Issue description: All Grids frozen

What happens: Tryining to search in the grids does nothing, the grid just stays as it is. New items thrown into the system don't apear on the grid, but the disks are filling. Still can take items out of the Grid and craft in it. Tried to rebuild the system still doenst work. Even if just the controller and the Crafting grid ist there it shows the items in the grid. Even built a new controller and Grid, and still the same issue

What you expected to happen:

Steps to reproduce:

I can't do anything with bugs without reproduction steps.

hard to tell when there where no certain steps

it apeard out of the blue, the last thing i did was attach an exporter and importer to it, to get lootbags out of the system and pump the items bag in the system

Then try to reproduce and then report back. Easy as that
