Possible bug - not sure if this is the intended dialogue or not. Doing Frisha's questline, swapped the wine out after Dave put the "potion" in it. The next time she came over, when he gave her wine, she made the comments that it just takes like regular wine so it seems to have worked, he did not successfully give her the corruption potion (aka MC's load.)
HOWEVER - the next day, spying in the mayor's office, when Dave comes over he says yes he gave her the potion "and it seems to have worked" - wtf? Is this what is supposed to happen? I thought he was supposed to bitch about it not doing anything. Also the mayor did not say anything about not being able to get more (and I never sell loads erm I mean potions to Lucius, so the only one he should ever have had is the one you have to give him at the very beginning - the sample.)
Also, do you still effectively have to progress Emily / Mira & Frisha's mom, to progress the story and upgrade your house, etc.? (Hoping not, because I hate the older LIs and I really hate how she starts trying to crowd in and join the fun when you are banging her daughters, but guessing you still have to deal with her.)
