The Witcher 3 has a butterfly effect. If you type addfact(q104_completed) for "Family Matters" without doing the preceding Velen main quests, you may permanently break the main storyline. You will lose access to the Crones, the Whispering Hillock, and multiple endings.

Have a specific bugged quest? Type listquests in your console, find the ID, and apply the methods above. Good luck on the Path.

| Quest Name (In-Game) | Internal Quest ID | Complete Quest Fact Command | |----------------------|------------------|-----------------------------| | Family Matters (The Baron) | q104 | addfact(q104_completed) | | The Last Wish (Yennefer) | q302 | addfact(q302_completed) | | A Towerful of Mice | q204 | addfact(q204_completed) | | Now or Never (Triss) | q209 | addfact(q209_completed) | | The Isle of Mists | q310 | addfact(q310_completed) | | Through Time and Space (Avallac’h) | q505 | addfact(q505_completed) | | Reason of State | q206 | addfact(q206_completed) | | Scavenger Hunt: Cat School Gear | q201_cat | addfact(q201_cat_completed) |

Forcing a quest completion mid-dialogue can leave characters in weird states (e.g., Geralt with his sword drawn permanently, Yennefer floating, Roach stuck underground).

Using the console disables ALL achievements for that game session. To re-enable them, you must restart the game completely (close and relaunch) after saving.
