Not sure if I'm doing it wrong, or it's a bug, but using the ampule doesn't seem to do anything. Like, I will break it once the signs of the zombification begins to show, but after that it doesn't do anything. I do have mods so maybe that causes it - More Traits (and I use the Super-Immune trait, I just don't want to wait forever). Anyone else got this problem / know how to fix it?
