So I ended the main quest and also completed both the 'Hearts of Stone' and 'Blood and Wine' expansions long ago. Untill recently I decided to complete everything that's left including side quests, treasure hunts, witcher contracts, undiscovered locations etc.
Then in my quest log I found this 'Novigrad Closed City' side quest incomplete. It says I have '1' key out of three and find the others. I didn't remembered starting this quest although I may have picked up the key in some other quest triggering this side quest.
Now when I tried to complete this quest I found the second key in the house where a dead body is lying and the chamber opens up by lighting a lamp. There's a chest which can only be opened if you have the third key. The quest instructed me to go to bridge where I can find the third key. But It was nowhere to be found.
I looked up in the forums to solve this issue and they say you have to save a man named Walter (I am not sure) from witch hunters and then he gave gave you a letter or something. Then you go to that bridge and find some lady and you help her and she gave you a key ( I am guessing it would be the third key). But when I found this guy, he was endlessly beating a door, the witch hunters were nowhere to be found, I can't kill him to retrieve the letter nor I can find the lady on the bridge.
Please help if any of you know how to solve this. I am going for a 100% completion and this particular thing is bothering me so much. It's so frustrating and sorry for this long explanation.
