Ok, what's up with balticrawlers?

So I've been playing as the bugs and I'm under the mountain, this is my fourth time with them and I cannot figure out why I get different results from my balti pastures. They are all the same size, all the same moisture, all same skill%, all same number of animals and ranchers, all same yadda yadda... HOWEVER, I always get one of two results for yields: 1.2 meat/day or a number I believe is correct based off my tech (35+).

What keeps causing the 1.2 meat/day pastures? I have deconstructed them and then built them again. I have copied only the successful pastures as blueprints. I have made sure everything is the same across the board, but I still keep getting this 1.2 meat issue (and like 0.0056 livestock/day) result at least half the time. The fact it is always 1.2 and not, say, 7 or 13 or 22 or whatever is suspicious as well.

Is this a bug or am I doing something wrong?
