I'm, honestly, undecided right now: I planned my next chapter 10 to be the story from Risky's point of view and how she returned to the past, then continue with the battle in Ch.11.
But maybe it would be better for the flow of the story to continue with the battle and put the flashback after it? It would also make for a smoother reveal of Shantae's amnesia and nightmares.
Either way there would be delay of no less than 2 weeks (likely 3) as both chapters are far from completion.
