It looks like the barkeep’s intro wasn’t playing properly at the bar, and having viewed that is a requirement of the scene. (As one of the paths ends up with the two of you at said bar.) I’ve patched a fix in for that with version 0.33.11, so if you visit the bar and then go back to Beatrice you should be able to see the scene. The other extra requirement is the intro scene with Claire and Skirts and More, if the bar thing doesn’t fix it for you. I’ve also fixed the victory scene with the sorceress in the river dungeon. I used the wrong penis variable, so it automatically defaulted to the large penis version. Thanks for reporting those.
As for the alley duo, when you say you can’t talk to them, do you mean you haven’t even gotten their intro event? Or just that you are stuck at a certain point in their scenes? If it’s the second one, what point are you stuck at? Their events should trigger just by getting near them, so you shouldn’t have to directly talk to them. Also, you can only do one of their events per day, so you could try going and sleeping at the bar and then returning to see if that fixes anything.
When entering the blacksmith, your class is changed to adventurer. When you then go to the sorcerer's cauldron, it changes to sorceress. You must have somehow avoiding your class changing, based on you having the "special" option instead of "magic," which would leave you with no skills. I haven't been able to replicate that myself though.
