Okay, there's a complex free waste production loop involving poison shots that can result in free waste production and thus free nrg for veggies.
Your veggies are very poisionious. They are shooting each other with nrg feeding shots (which cost nothing in your sim) but the shot doesn't get through the poison ( so no nrg is actually lost from either the shot or the impact). Instead, they release posion shots (which target .shoot, re-inforcing the loop). They loose poison when they shoot it, but because theye are conspecs, they gain it back from each other when the shots impact. Waste is produced when a posion shot is generated (for some reason predating me) and your veggies are turning this free waste into free nrg.
I'm inclined to simply not have waste produced when a poison shot is fired. Waste is already produced as a result of manufactoring poison (as it should be). Inorder for there to be conservation of nrg in a sim, waste must be thought of as a form of converted nrg and therefor only be produced as a side effect of some action that consumes nrg. Shooting a poison shot consumes poison, but not nrg. Yes, it takes nrg to make poison, but waste was already produced when that happened and in the case of conspecs, that posion is not necessarily lost to the system. Producing waste both when poison is made and when it is fired is double taxation magic production.
So, bottom line, producing waste as side effect of shooting poision (as opposed to making it) violates the principle of conservation of nrg, especially when conspecs are involved and the posion is not lost to the system.
Fixed in 2.43.1L. Waste is no longer produced as a side effect of shooting poison. Only as a consequence of making it.
