I noticed an issue with the fields that you start with on new farmer, it shows on the map that nitrogen is good but display when walking over the field shows “nitrogen not valid” or “nitrogen layer not found” or something like that.
Without Precision Farming, Fert = 0%, and with Precision Farming, "No Data Found" without the soil information. But once you buy the soil information, then data is populated. So, I cannot replicate this issue again. Possibly a mod conflict? Or try scanning the soil/buying the soil information. Thanks!
