Kiln/Furnace remove wood/ore from storage but won't activate

[BQubed]

If I have wood/ore in the container, the kiln/furnace will pull the wood/ore but nothing else happens and the following errors are logged:

[Error  : Unity Log] NullReferenceException: Object reference not set to an instance of an object

The following are the only config settings I have that are not default:

## If true, will pull fuel from containers.
# Setting type: Boolean
# Default value: false
PullFuel = true

## If true, will pull ore from containers.
# Setting type: Boolean
# Default value: false
PullOre = true

## If true, will pull cooking ingredients from containers.
# Setting type: Boolean
# Default value: false
PullCooking = true

## The maximum range from which to pull items from
# Setting type: Single
# Default value: 10
ContainerRange = 30

The furnace is still able to pull coal from storage and successfully store it. The wood and ore is lost however.
