Great, yup! All of that is expected.
Updates to the dice window are next on my chopping block, but it's awesome to hear you actually got your actions times quicker than the dice rolls.
The 200kg stone is supposed to be a long-term goal that you don't tackle for a while yet, hehe. The mining will get a bit of an overhaul shortly too, though, letting you purposely aim for materials that you need, among a smattering of other intended changes.
Thanks for sticking with it!
