screen goes black but doesn't crash game

[teaofcups]

Here are two saves, one is where the screen is already all black.
The other is one where the note is about to be read, you just have to click on it.
They're not the same situation, the latter is a different place and a different note but the same problem occures.

I just go from room to room picking up all the usefull items like oil and tinderboxes everything use the head/helmet to break open the wall.
go through read folklore note, solve the book puzzel take the key and the last note I read is in I think the study where the one door is blocked.


I did at first skip going to the lab and cellar in favour of the archieve but after the black screen I reloaded and did the Lab first but that didn't result in a different outcome.

I hope this'll help.
