What is happening:
At the end of the dialogue with Honey Glace, a second dialogue window pops up and it says "I need to hand out all the samples."; the title of it is "Objective". The quest doesn't appear anywhere in the quest book. There is also no second dialogue with Honey Glace (the dialogue contains four sentences from Honey Glace). Also tried it with another character; didn't fix it.
What should be happening:
I'm pretty sure that what the window says should be a Quest title.
