I have no idea how, or when, this started. I just tried to do some bur farming and realized that where the spots on the map are, there aren't any bur weeds. Then I took a broader view of the entire yard and realized that I no longer have ANY spiky bur plants anywhere!. I reverified the files through Steam and nothing changed. This is bad since I was wanting to change from the clover roof to the new pinecone roof and it uses burs.
