Expected Behavior

Conveyor placed into GUI slot for a machine would act as configured

Actual Behavior

Conveyor placed into cover slot in machine GUI continues to export after being configured to import.

Steps to Reproduce

After going through the rigamarole of entering a new creative world:

1. Place down an Alloy Smelter with a chest on the top (To become Input) and one to the back (To become Output)
2. Configure Alloy smelter to auto-output to the back.
3. Open Alloy Smelter GUI, select the top face, and place a conveyor into the cover slot.
4. Open the configuration pane for that conveyor in the Alloy Smelter GUI, and set the conveyor to Import (into the Alloy Smelter)
5. Fill the input (top) chest with 1 stack of Copper ingots and 1 stack of Tin ingots.
6. Upon completion of the Bronze alloying recipe, the Bronze will be exported into the top chest, despite the conveyor having been configured to import.

Additional Information

While similar to #1071, this is likely a different issue - relogging solves the issue consistently.
