I think I may have run into a bug? I've made six Heat Occisia for Bernard's fever, but nothing happens when I go to the Shop besides the 'Leave' option.
ANSWER -> you need to use the heat occasia to make spectral syrup and cure bernard with it,also has to be during the day,go to your home and look at the recipe for spectral syrup and make it accordingly and give to bernard,will complete quest and start the next (well at least open up more after)
