Modded Npc bot appearing in my game- HELP

So I downloaded the Mirren the Florist NPC mod but no matter what I do he doesn’t appear. I downloaded it and I don’t get any errors on my smapi about him. He is in ny mod files but doesn’t appear on in game nod list. I don’t know what to do, I deleted it and redownloaded it and it is the same. If it matters I added him on a current play through on second year, not a new one but I don’t see anywhere in the mod description that says we can’t do it. Please help.
