I think Y'shtolas 2nd 'accident' was quite good.
First, it didn't happen at 77 and then about 15h later we get a cutscene spoilung her survival for the next patch cycle.
It took less than 1h to resolve the issue.
Second, it was really important for giving Emech an opportunity to recieve 'some' trust, while also showing his powers.

I really liked that something which made us worry for several patches last time was undone with a 'single snap' (quite literally).
