Worked out the optimal crop rotation and immediately stopped enjoying the game, so I have deliberately forgotten it.

This is a known hazard and I walked straight into it. The moment there is a correct answer, everything that is not the correct answer becomes a mistake, and a farm where every decision is either optimal or a mistake is a job. I had a lovely inefficient farm and I solved it.

Started a new save last week and I am deliberately not looking anything up this time, which is harder than it sounds when you already half remember the answer.
