IMO the biggest problem with removing Padme’s death is how, if you watch it in chronological order, it doesn’t work. We’re left with Padme being alive and then she isn’t addressed for two whole films before it’s just unceremoniously said she died.
This lucas’s fault in the end leia having memories of padme is a plot hole that didn’t have to be.
One day people will stop throwing “plot hole” around for every movie-related complaint they have.
Adults claim to remember things from their childhood that they’re sure happened all the time, even if they provably didn’t. I’ve never heard any argument on why Leia should somehow be exempt from this phenomenon outside of fanboys wanting another reason to rag on Lucas.
Leia, as a grown woman, vaguely recalling non-specific memories she wouldn’t have is far from a “plot hole.”
