I can't exactly provide a screenshot (I don't know how, sorry- I feel stupid enough >^<) but the rows kind of look like this:
f w o a
f w o a
f w o a
The letters represent tiles with crops, they go from northeast to southwest. I know this isn't a very good representation, but I can't really provide a screenshot unless someone tells me how. The O is the only crop I can farm, which I found out was beetroot, not red onions (sorry again).
As I was typing this, I tried to harvest my crops, and the problem solved for some reason... Sorry for the trouble.

(P.S I checked and I did have all the skills to harvest crops and I did at that time use Adventure>Landscaping>Harvest Crop)
