How can my pollution kill them‽ Their nests absorb it in huge swaths and actually give birth to MORE of them not less! /s very, very much (because although I didn’t know the player even had any kind of external alignment in factorio until right now I can totally see and understand this being the canon response of the devs thus making my statement rather sarcastic!)
Except you already have that update installed, the box is not checked and the entry is still respected, nobody could possibly tell you why because that’s not how it’s supposed to work and everyone else works as stated! And now you have to live with the knowledge that your system is in some unobserved quantum superposition with a critical fix in place which may stop working at any moment for any reason and nobody can tell you how you even managed to get into this situation…
