I can't speak to this update's Rastedel events in particular, but old saves regularly DO break later events (And sometimes the game entirely), often due to missing flags. There was at least one (Probably more, I forget) previous incident of this for Rastedel, and while you can sometimes fix these issues by looking at the files to figure out something that needs to be set to true/false in console to continue event lines, for Rastedel it is...most definitely not worth it trying to figure that out.
If your events aren't continuing because of an old save issue, for Rastedel at the very least, possibly best to just play through game again (Keeping in mind that the same thing could happen with the next update.) It could also be something else, since there are points when the Rastedel continuation is an event back at the castle, but while I can't speak for the new Rastedel events, these are I think easy to trigger as, "Go back to castle, wait a week."
Not sure about Fey Court though.
