Reproduction:

I built an entire plumbing set up that grinded omega weed filled with ammonia, nitrogen, and oxygen, into a chemical slurry. It worked properly for about 1 cycle of the acclimators turning said chems into N2O when the whole thing stopped. It seemed the acclimators were still functioning and heating some chems, though that might have been an issue with my set up. The issue was the plumbing grinders didn't grind any of the plants anymore, there were about 15 plants on their tile and no chems got added to the grinders. I even tried moving more plants onto their tile via a conveyor belt, but they still didn't work. This all happened at about an hour in.
