This sounds like a nightmare for production lines. Items on belts just randomly turning into spoilage? I hate thinking about how this will break so many common factory setups, and I like this change just as much for that same reason. Just filtering out spoilage at the end of a belt won't be enough for some designs, especially when 3+ ingredients are involved in the recipe (so two input belts). It'll be interesting to come up with new designs that can filter the inputs mid-belt to remove the spoilage, since it's inevitable if your inputs come faster than you can process them.

Can't wait to see the update.
