That makes a lot of sense. Grievous receiving orders about moving to Mustafar always felt like it was moved up earlier in the film, since it’s a good while before he actually does.
I feel like LOE reverts the movie to an earlier version, largely, and I’d love to see an older rough cut.
I liked how you removed Palpatine giving Grievous the orders to move the Separatists to Mustafar. I like the idea that Grievous is making the order himself, but the Separatist leaders cannot escape Palpatine because he knows their location due to being a Sith Lord.
