So Im replaying Skyrim, and aside from its normal minor bugs everything has been going well up until about halfway through the Thieves Guild Questline.
Issues started after 'Speaking With Silence' where 'Hard Answers' wouldn't trigger, and only sometimes would advancing the quest via the console with 'setstage' would it work. Once the quest was force-triggered, it ran just fine. However, at the end of 'Hard Answers' Karliah would just walk away and I would be able to trigger 'Trinity Restored' unless I forcibly moved her with player.movetome to force her to start the scene with Brynjolf. And as with 'Hard Answers' the quest worked just fine afterwards. Now I've reached the end of 'Trinity Restored' but I can't trigger 'Blindsighted' and the console commands will not work. I've tried replaying this section close to 10 times and I can't figure it out. On a whim I loaded Skyrim via Steam (I was previously playing it with SKSE) and managed to get 'Hard Answers' and 'Trinity Restored' to trigger just fine, but still no luck with 'Blindsighted'.
Anyone else running into this and found a solution? I've seen one other person make mention of this issue online but no one responded to their issue. Any help would be appreciated.
