If you place a valid recipie in the super wireless grid, close it, then reopen it, the recipie output will be blank. Taking an item out of the grid and placing it back in does seem to fix it and get the recipie to regognise but this will only fix it until you close and open it again

The block based crafting grid from RS seems to work fine but the wireless crafting grid from RS does have the same issue

Result of putting items in:

Result after closing and reopening the grid

For context this is on version 1.1.0 of the All the mods 8 pack and was not present in previous versions.

It uses the RS api to open the grid and if the RS addons one is having the same issue it's likely a result of another mod or an issue with the RS api, Could you try this with just RS and RebornStorage installed?
