Some of the mod's central functionality is not working. I've started a new world, with all settings values at default, and when I place down a furnace it doesn't get autofilled with fuel.

Do you have fuel (coal, rocket fuel, etc) in your inventory? Is it a stone furnace or a steel furnace?

Yes, coal, and it's a stone furnace.

My apologies, I missed that you didn't have SpaceAge enabled. It was not working in non-spaceage. Fix incoming.

It is fixed, thanks for the report!
