Even as I type, I had to skim through the film to remind myself that the Kylo-Palpatine conversation had been moved from heading to Endor. And it introduced a continuity error I don’t believe anyone picked up on until you did.
Perhaps the simplest fix would be to replace or remove the line, “I know where she’s going.”
But that’s still true, isn’t it? Now, it refers to the Knights of Ren tracking them through hyperspace. I actually thought that was a really clever way to repurpose that line.
Since he is helmeted during that scene, it does give some wiggle room. If possible to splice some lines, he could say something "My Knights are tracking them/her|My Knights will know| etc.
