Ok, so, my reason for asking is a bit complex and convoluted, so bear with me.
I saw that if you let Lumi harvest you 5 times, it triggers an event wherein she doses you up with some of her special juices that give you Breed Hungry and sends you an email.
Since I'm an ocd completionist, and I was bored, I wanted to do this event, but I already had the Breed Hungry perk from somewhere, no idea where, may have save edited it in, doesn't matter moving on.
Point is, my player characters incubation speed is so fast its almost game breaking, and I'm worried that even if I save edit the initial Breed Hungry I already had out, something may stay behind, so that when I get it again from Lumi it will stack.
And so next time my Steele gets preggers, the poor kid will go from single cell to crowning in 5 minutes.
I compared the incubation speed stats from a save file before and after I did all the hullabaloo, and they looked the same, so I think I'm good?
