I have the same problem as in the original post only the solution proposed by Bonezz.4961 does not help.
It keeps telling me i have to go collect the herbs when i interact with the cooking pot which is now green on the map, but i do not see them anymore as Bonezz.4961 posted above with his screen shot.
EDIT —-—- UPDATE —-—-
Correction, i was trying to put the ingredients in the wrong location, just as Bonezz.4961. Please see nottsgman picture for details.
Also i tried stopping and “continuing” the episode again which did not help.
I have also reported a bug in-game for it.
