(spoilers for Star Wars)
It's not EU, it's canon and it happened in Rebels. Ahsoka Tano was saved from death by a time traveling Ezra Bridger in Rebels. Really.
Maybe even this could be swept in the rug under the endless pile of Star Wars stories, but with a new Ahsoka Tano tv show announced and rumors that Aladdin star Mena Massoud has been cast as Ezra Bridger, it seems this time travel business is probably going to feature in a huge way in that show (I mean, they'll probably mention how Ezra saved Ahsoka by time traveling back a few years in the new Ahsoka show)
I don't see why her death couldn't just be ignored (as in not talked about), for anyone who hasn't seen Rebels?
