Oh I never got that far cause somewhere along the quest line it bugs out
A while ago it was because the illegal potion guy acknowledged the that I needed herbicide but I needed to do him a favor, then didn't give me any favor to do...and last patch the husband AI seemed completely broke and the illegal potion seller didn't even acknowledge the herbicide questline. So idk maybe better luck this patch? But even just now I had the illegal potion seller brick just doing the sweet potion quest. I could go on about how other quest lines/NPCs have just stopped cooperating permanently but it is what it is I guess.
Anyway thanks for the response at least now I know
