Posting a few pictures for you/Crate to take a look at in the hopes this helps with what’s going on with cows and eating your fields. The first one is how the fields look when the barn is selected. Notice that all but the two fields in the middle and middle-left are lit up as having fodder quality, while the two mentioned are completely null and void.
In the second picture, you can see the Set Grazing tool being employed. The fact that the fodder bonus is 47% shows that these fields are likely set to 0% fodder quality, or were somehow blanked of being grazeable when they were completed. Since it happened to only two of the nine squares, I’m honestly thinking this is a bug with the game as others have been posting here about. I just wanted to give a visual explanation to better assist with unraveling this particular tangle of yarn.
