There are a few developer console commmands you can try out for buggy quests:
Merrill's Companion Quest - Act 3
There's a bug that prevents Merrill's Quest from being obtained/completed. When Merrill is visited at her home, a cutscene immediately takes place. However, this is due to a bug/glitch and will prevent the player from getting her quest later on. The resolution is below.
- runscript zz_mrl_debug
- Select Main Quest
- Select Act 3
- Select 1 - Start Merrill Notify.
Merrill can now be contacted in her home, and quest can be obtained/completed. It is best to complete the quests 'A Talking To' and 'On The Loose' prior to using the console commands to stay with the chronology and avoid immediate termination of those quests.
Fools Rush In - Act 1
There is a common and frustrating bug where if you loot the letter from the mercenary's body in Fools Rush In, you will be unable to enter the Chantry to confront Hayden. It can be fixed in the following manner:
- runscript zz_isa_debug
- A menu will appear. Select Plot.
- Select Fools Rush In.
- Select Plot Point.
- Select Hayden Encounter.
You will skip some dialogue, but the quest will complete as normal.
Isabela's Companion Quest - Act 3
There is a relatively common bug where Isabela's quest cannot be received in Act 3 Hawke Estate. To fix this:
- runscript zz_isa_debug
- You should find yourself in a menu. Select Plot.
- Select No rest for the Wicked. Act 3.
- Select Jump to Plot Point.
- Select First Velasco Encounter.
This fix means that a couple of dialogues will be skipped, but quest can be obtained.
Aveline's Companion Quest - Act 3
There is a bug where Aveline's armor upgrade, Deflecting Joints Guardsman Pattern, can not be found on Jeven. Here is the workaround:
- Get AddItem-Mod from here: [1]
- Open console
- Type in "runscript additem gen_im_cns_flu_aveline_04.uti"
- Alternatively you can download an unofficial bug fix here
