Hello everybody, i really need some help here.

I've tried and tried, every by restarting the chapter from an earlier save but in no ways i am able to get through it.

I've interacted with everything possible but somehow the game keeps insisting that i am missing something in Wagner's Museum and Neuschweinstein

I am 100% there is nothing i am missing in the Castle , so probably is just something in the Museum but no many hours i spend clicking on everything i can, i am still not getting that final clue that would finally lead me to the end of the chapter.

Unfortunately i am unable to check Youtube for some video walkthrough due to reasons and i'm not getting any help from walkthroughs i find online. Anybody has any idea what i may be missing? Maybe a aprticularly hard to spot area that somehow i fail to notice?

This is driving me crazy.

In the castle there's something you have to click on twice, or you have to use the tape twice for something. In the Ludwig museum there is an easy-to-miss display case below the painting that reminded Grace of her nightmare.
