Career Path Missing

chef and mixologist are both branches of the culinary career, if your sim is already a mixologist they are past the point of chosing the branch, they already chose mixologist ( I think it's level 4 or 5).

I would quit job and start in a different career than culinary, then quit that and go back into culinary, I think that way your sim starts at a lower level than 4 again and you can chose the other path when you get to that level.

Or you could use a cheat to cheat them down.
