Hello! It is indeed a bug in version 1.4 :(
It is fixed in next versions. You should still be able to progress on this quest by going in alone though!
Thanks for the answer. The solution helped, after I reencountered the bug (needed a few new playthroughs but I wanted to test it).
Oh, and since I forgot to say it two days ago: They game is fun to play, and the porn is written nicely (at least imo as a non-native speaker).
