Questão Roast Duck Problem

Making Roast duck is a breeze, but am unable to sell it to Exchange.

...And speaking of exchange: most of what I add requires two taps on Sell Goods, to get the list of available items to come up. When I went to debug mode, it took every one in, turn, one click, each. Go figure.

Roast duck should be there if the Exchange is of type Grocery or Concessions (see lower left on the green border) Some things require the exchange to talk to the Quintonia server and I've noticed it can sometimes take a few seconds to do that. You can tell when it is talking to the server as the entire screen goes green, so if this is happening for you then just wait a few seconds longer

Ok.. noted. Thanks.

As for having to click the Sell, twice, I forgot to mention that it shows 'Nothing nearby' or whatever the wording is, as well.

Oh that's odd - so you mean you click to sell and it comes up with nothing found nearby then you click again and it finds it?
