Before the update to stacking in the star menu this quest used to read:
"Complete the "Country Saying" collection by gathering all the required ingredients! Why are you still reading this? Get going!"
• Produce at least one "Country Saying" at the Mayor's House and use on one of your Fields.
"At long last! It is completed!"
The requirement made the action clear and when the first part was done there would be a "Country Saying" refill buff in the Resources tab of the star.
Since the star menu update and the vanishing of the specific "Country Saying" buff in the star the quest has been altered, but not in a helpful way. Now, it is completely confusing:

It doesn't explain collectible buffs are made in the Mayor's House, in the image it doesn't even show a "Wheat Refill/Wheat Mine" but an "Omni/Any Deposit Refill".
The quest can be completed without actually producing a "Country Saying" in the Mayor's by using a refill got in trade or elsewhere, but that seems to miss the point of the Collectibles quest chain and as a piece of the "Tutorial" the instructions on this could stand improving. See any number questions about 'How do I... with the 1 wheat... o.O?' in assorted Help tabs.
