After I bought pig hearts and eyes from the butcher in Flotsam and went back to the old hospital ruins, the Nilfgaardian ghost is no longer there. I turned the whole old hospital upside down and he is nowhere to be found. He seems to have disappeared.
So where do I find him?

Please help.

Thanks.

He should be right there where you left him, in the room with the ladder (where you can descend to right out of the room where you met the first two wraiths). If he is not there, I guess it's a bug.

Do you have a savegame (or autosave) BEFORE going in the first time? Try to redo the first part of the quest. And don't bother with the pig parts, because they give the same result as nekker parts and I guess you have some of those in your bag.

Yup getting pig part gives the same result as nekker parts even if you drop the nekker parts before getting the pig part

I really like people who ask questions and then vanish and never report back if their problem is solved. Or, you know, say thank you, like polite people.

Some are like that. : ) I think that is the one where where I just took the two guys back to the Nilfgaardian Ghost. ( " Come On, I have something to show you" ) HeeHee. : )

Then it's a bugged quest it is.

I thought the pig hearts and eyes would yield a different result, like, successfully deceiving the ghost.

I think I have deleted all the previous saves, too bad :-(
I don't like having so many saves, they bog down the performance.

By the way thanks for the swift reply. I hope CDPR fix this quest soon.

P/S: Well you can't expect everyone in the world to be on the internet 24/7 or F5ing a forum thread page every 10 seconds waiting for their problem to be solved now can you? People got social life too. Chill, bro.

Well, I'm not your bro and after two days it looks as if someone is not coming back - as a lot of people do it, when they don't get their answer within the first three minutes of asking. Apologies for assuming.

It's always a good idea to keep the saves of the day around - I have a backup folder, were I put my saves in and where the game doesn't look, so it doesn't slow it down, but they are still available in case of bugs.

You are the first to have this bug around here, so if you want to get it fixed, you should let CDPR know, they can't fix what they don't know. http://www.en.thewitcher.com/support/

PS: if you tag your OP as a question, you also mark it as solved, when you get your answer, so more people don't come running, trying to help. ;)

Nope.
Still not fixed in the latest v1.3 patch.
The ghost is still missing.

"50. A progression break in the ‘In the Claws of Madness’ quest has been eliminated."
What does this even mean then?

I had great hope when I first saw the v1.3 patch change log, now, kaput.
