Miners might, uh, kinda hate me for this.
I can't not do this though. It just has to be.

Can you spot the hazard?

Took me a second, but I love it.
The mining catwalk runs afoul of the external crate delivery routes now.

Although, with the belt right there, could we get a little routing thinger to send crates to/from the little mining department?
