If you are experiencing the bug during the "Emogene takes a lover" quest in which she disappears from Charles View Amphitheater and you are extremely annoyed of find every time the set of command to fix it, here it is a simple .txt file that you can use with the "bat" command to fix the issue in just one second. Download and unzip the file then copy and paste "cabotfix.txt" in the Fallout 4 main directory. Now you have just to open the console and type "bat cabotfix" (without inverted commas).

Edit: This fix will only skip the part of the quest that needs Emogene, it WILL NOT make Emogene appear to talk and she will return to Cabot House only after killing/freeing Lorenzo.


P.S.: I'm not english so you don't have to worry if my English is a mess.
