I was stuck on how to make Fertilidust because I missed the bit where it tells me to buy an ore grinder & beaker - I accidentally refreshed the page just as 'Completed:Refining' or whatever skill it was, came up & Rock gave me a new quest when I came back.
I had to ask around in the Help chat (thanks to you guys who helped me with that).
Im suggesting a little button that says 'Replay Instructions' or something along the lines of that, in the Rock menu.
