^What makes you think that? Did you read that somewhere?
I’m actually really glad that they didn’t explain how Maz has the lightsaber. No explanation would have been sufficient or necessary. Some rando EU book can do that.
There have been some people on reddit reorganizing various rumors and leaks which seem to be possible deleted material, Starwarsnewsnet had reported that there was some Cloud City flashback in the movie, which most likely was legit since they hadn’t been wrong before and even leaked Luke’s appearence.
MSW also described a different scene with Finn, Han, and Rey together seeing a longer version:

I’ve been going pretty far, and it was surprising to find just how accurate most scene descriptions were back in January/February.
