Yes, feldspar can be found on surface boulders (quite common), mining regular rock (relatively uncommon) and gold veins (quite common). They’re also present in traders, but overall I’d say there is more feldspar than gold available in the world so it shouldn’t be much of a problem - I guess Ball Clay will be more difficult to obtain than feldspar (unless you’re playing in the desert, where it replaces the common clay) but still relatively common and available in large amounts if you dig in the right places - and also available on shops. Porcelain has some furniture that is a bit more worthy than ornate wood (more appeal and value) so the challenge level is also a bit higher - either way if it remains too difficult can always be tweaked to produce 3 pieces instead of 2 per craft, which would make it quite more obtainable.
Finally, I think that these end-game crafts would benefit a LOT from those ideas we discussed in Discourse of being able to (at least) select the trader type you want with a “higher tier”, larger Market Stall
So that’s something that I’d really love to see happening and should probably help a lot for players with mega projects or ideas for making entire towns based on rarer and more valuable resources!
Aww, I’m sorry to hear about it! Yes, logs and dumps would be really appreciated in this case - I don’t know much about Macs and as far as I know there shouldn’t be any issues since in theory mods can’t affect the compatibility which is done on an engine level, but might be some edge case or other unrelated issue!
So if possible, please provide these
