One thing that no one has yet considered in terms of fan-edits is the fact that there is a FULL HOUR of stuff that was cut out of this movie. I recall the actors being surprised that entire full sequences they shot for weeks were lifted out of the film completely.
So there may be things on the cutting room floor that might speak to plot holes and logic problems we have with the story itself.
And why the hell couldn’t it be Lando Poe was calling to get help with finding a codebreaker? That would so fit with the character and Billie Dee could have done it with gravitas - PLUS it would give us a hope that Lando has a few friends of the Resistance still out there. Missed opportunity, and better.
