Already had to remove them. Yes, they caused weird things
I have it running but need to test it a little more before I call it fixed.
They have changed the animations sections too, so was initially invisible.
I've got to go to work but i'll poke away at it over this week and let you know when it going fully.
I've changed the recipes to use 2x the base furnace instead of the raw resources. This allows easier automation of production and also allows for players who carry the base furnaces around pre-made.
