Not sure if this has been mentioned in this thread before, but just a niggle regarding the Shaak Ti death. She does actually appear later on in the film during one of the Jedi Council scenes, though if I remember correctly it was in hologram form so it could be feasible to edit her out.
You might be thinking of Aayla Secura. I’ve personally never noticed her appearing anywhere else in the film.
No, definitely Shaak Ti. As a hologram during a Jedi Council session. Very brief but she is there.
