Hi there, I've just tested the Smarter Farmers mod (Fabric 1.21.1) and realized that they don't just plant crops on farmland, they sometimes just randomly plant crops on grass blocks around the naturally generated farmlands. Which leads to randomly growing crops throughout a village.
This issue has been around since 1.20.1.
An example image of the issue has been provided (the random spots of crops around the naturally generated farmland were planted by farmers).
