Hello, I am writing for Freebie TFC cant harvest crop problem.

As I tried to harvest those crop in my town [CHorse],
I destroy the crop which were grown with hand only,
Nothing was dropped.

I guess maybe the planting of my soil is too long long time ago,
so I plant them one more time and this time destroy with my hoe
still Nothing was dropped(even the seed/crop)
Recently, I saw the wild crop which was grown too,
destroy it and Nothing was dropped

These are All the situation that I can try already,
may someone help me?
