I think I found the cause of the problem.
The bug started on day 5 , where the previous extended demo ended.
I did 3 new, fresh routes to day 5 and it worked great. The laptop worked and I could read the story, no bug or error.
But as soon as I loaded into an older safe file where I left of, it's where the bug starts.
I had multiple old safe files with different variants and no matter which one I choose all of them end on the same bug. But If I do the same routes from a fresh starts everything is fixed.
Here is the answers sorry!
It was day 5, the first tube was red, the second was green. I was clicking trough the story manually, no skip or auto play were used, yes it was a save from the demo.
