MasterofFiction: Thanks for making this. I wish I had seen it sooner. I never finished this game because being unable to complete that one broken quest just bothered me. Maybe now I can actually finish it.
Wait, I need a Nexusmods account in order to download it? Sigh. What is with the internet these days. Need a million garbage "accounts" to do anything.
Edit: Well I eventually did try it, and the broken quest still will not complete. So that was a waste of time. Thanks for trying anyway.
The reason the quest is still broken is that you already broke it before installing the patch - the fix isn't retroactive, it only works on new instances of the quest. So for anyone doubting the patch, it works fine, but play on a fresh save to avoid user error issues like these.
