Now this ‘plothole’ about the spaceship leaving Jakku is nitpicking! You want an example of a pedantic nitpick, here is one!
This spaceship in the background is a tiny moment you have to freeze frame during a vision. I suppose Rey being on Cloud City is a plothole too - because I saw her there!! The whole segment is a vision, it is NOT literal. Even if you are taking it literally, then who is to say that her parents were on that spaceship, it’s entirely assumption (bit of visual misdirection hardly warrants it being canon now does it) - a plothole? Don’t make me laugh.
Did you miss the part where a little girl dressed exactly like Rey screams out at it “comeback” and Unkar tells her to be quiet? The girl is screaming towards the sky and Rey turns to see the skip flying away. It then transitions into Starkiller base (which also happened).
It wasn’t just a freeze frame moment, it is made to seem important. Again, it could be misdirection but two other parts of it have been shown to be true.
