Yep I've got a little sub level under the house for storage chests & then i've burrowed down. I'll make more chests & drop things in there to help with the materials cause.
Only problem I have at the mo is I need more coal for torches & I've not found any in agessss.
Ah i have some spare coal

I am always finding it.
I use the same name in game so when you see me give me a shout and i will get the coal for you.
