don't have objects be both crushable and siftable

• absolutely not. This is intentional , and desired, to provide agency on what output a player might desire. I won't approve this change for the master branch.

Seeing lots of simple changes here, beyond that. What exactly is going on in the mmUpgrade change?

[giantcavespider]

the change with crushing/sifting was made before and I assumed it was accidentally reverted by a contributor. (the original reason for doing so was the precursor forge).
the mmupgrade change was just me realizing a previous decision was probably a bad idea.

I assumed it was accidentally reverted by a contributor.

Yes, your change is correct.

These 3 crushings have already been removed in #3404. @Argenttip accidentally readded them in eb3f8ca.

There were other errors in eb3f8ca: it added blackslimematerial (solid) to centrifuge and removed crushing of direstone (rock).

[Argenttip]

Black slime was added as per this list. I don't agree with some of the items and their processing stations, but I'm not sure how much leeway they're giving.

[sayterdarkwynd]

You don't need to agree: that's where they go.

"remove forced gravity from lush dungeons (will now use world gravity)"

For this change, have you tested the effect it has on the Dark Davern rope/jump areas? we can't provide a change to gravity if it nullifies the need for rope or the jump tech. That's the reason it had a set gravity: parity for all species.

[giantcavespider]

that's not for the dark cavern, it's for vina's lab and the overgrown house.
