Some additional data for the Market/Resource refiner question, for Kindle Fire:

My new village reached level 8. I upgraded the magic rock, now unlocking the ability to make stone (might be level 9 by now). I needed a storehouse and wanted the large storehouse, which requires stone, so I did, in rapid succession without waiting: Go to Market, see I can't buy stone, it's greyed out. Start building Stone Carver, Buy 500 stone at Market, start building Large Storehouse. Having an under-construction Stone Carver seems to be enough to buy/sell stone. Try to put under-construction Stone Carver into inventory - you can't. About 18 hours later, Stone Carver completes (now level 11). My stone balance is zero. I can buy/sell stone. Put Stone Carver in inventory. I cannot buy/sell stone. Take Stone Carver out of inventory. Make 1 stone, and collect it. Put Stone Carver back in inventory (sacrificing 98 rocks for this experiment). I cannot buy/sell stone, so having stone is not sufficient to buy or sell it. Take Stone Carver out of inventory, and make 50 stone and collect it. Put Stone Carver in inventory. I cannot buy/sell stone (stone balance now 51). Take Stone Carver out of inventory. Now I can buy/sell stone.

Conclusions: for Kindle Fire, having/not having a Stone Collector (even under construction is ok) determines whether you can buy/sell stone. Having a stone balance does not. Having *ever* had a Stone Collector does not.

I don't think Rock is a good way to test this, as everyone at least used to have a Rock Quarry.
