Been completing all major quests leaving some of the side quests from posts/random npc.
The only big 2 are Mysterious tower (killed the golem and only 9th sephirah left) and Vizima confidential.
I think with Vizima confidential game bugged, preventing me from completing it. Journal says to gather info from Leuvaarden, but when I try to talk to him, the only 2 possible dialogue choises are "how's bussiness" and "farewell". I read that some kid should talk to you about finding something, but been walking half a hour around the city and no boy appeared. Last time I've saw the detective was when he got attacked in his house and after saving him, he went into hiding. Meanwhile there is a quest related to Shani about talking to her...returning the favour or something, but been visiting her at the hospital and in her room but nothing has changed

The main quests in chapter 2 are sophisticated, with a lot of interdependences. Considering your minimalism, it's possible that you missed the one or the other trigger. So it's hard to say if you are confronted with a bug or if it's a simple pebcak-case.

If you don't (and didn't) use any cheats, mods, scripts etc. (this means: plain vanilla), then upload your savegame and post the link. I will have a look at it. It's easier than playing the game "Ten questions - ten answers".

Open your quest inventory, not the normal one. Find the "list of suspects", read it (RMB). Leave the Hairy Bear, the little boy will appear. Go to the detective's house immediately, don't do anything else (!!!).

Thanks for the help :)
