Bad issue report.

I believe I experienced the same thing with 1.6.4. Moved disks to another RS system, still did not show up in grid. I had just set up a "keep in stock" mechanism, and was about to add the crafting recipe for the item I wanted to keep in stock (vanilla torches). Was running in single player. Quitting back to menu and reloading the map did not fix the issue, but restarting completely did (whew!)
