I have LOTL 3 and I still don't get enough seeds everytime to replant. I harvested 14 corn plots and got back 10 seeds. Now of course that means I had enough corn to make more seeds, but it happens frequently enough that I am always making a few seeds each rotation. Maybe I just have bad RNG. Replanting doesn't take that much time for me, but I am only feeding three people. I have 42 plots at my main base (after recalling that mushrooms don't need a plot or a space next to each other.) Yeah, we do have to eat often, but it isn't gamebreaking.
