Expected Behavior

Fuel should stay in the fuel slot and results should be shift clickable out.

Actual Behavior

When using the oven, fuel consumption doesn't work properly. Placing a stack of fuel inside, closing the GUI, and opening it will result in all the fuel disappearing with the burn time of one item;
sometimes just placing the fuel inside will do it.

Items in either of the output slots also can't be removed.

Steps to Reproduce

Version of Minecraft, Bewitchment, Forge, Patchouli, LLibrary and Baubles used

1.12, Bewitchment-1.12.2-0.0.17.6, Forge 14.23.5.2807, Patchouli 1.0-16, LLibrary 1.7.17-1.12.2, Baubles 1.12-1.5.2

The same behavior is occurring in Covens Reborn. I shall see if there are any fixes I can use.
