watched the end of this stream.
Of course, after a 10-hour marathon, mistakes and other things start to happen.
Especially when the spellbook doesn't open at such a crucial moment, right before the timer runs out.

But, to be fair, after watching this episode several times, I've come to the conclusion that it's a bug with Hell, not with the software.
The spellbook should open when the mouse button is released, not when it's pressed.
In the stream, it's clearly visible that Hell presses the mouse button and then quickly moves the mouse away, meaning there's no release of the button. Then he starts to panic and holds the mouse button down and manages to move the mouse again before releasing it. And only on the third attempt does he fulfill the condition for the spellbook to activate: pressing and releasing the mouse button on the spellbook, and then the desired action occurs.

It's understandable, but I don't see any reason to replay anything.

P.S. As an alternative, this action could be attributed to the mouse sticking.
