Nice observations Burbin, especially the first one. That is a simple fix that makes more sense. Heck, from the beginning of the movie one he gives the order they shoot without hesitation … now I can’t unsee that issue with the DeathStar crew.
I admit for the current C3P0/R2D2 cameo, I did use Digmod’s approach to cut it out since I admit, although there can be an explanation about how they go from being on the base of Yavin, to boarding Tantive IV … which then eventually goes into Radus’ ship … but it’s more of a logical assumption than a reality that makes it more of a hole than anything.
So yeah, logically we can rationalize how they get from Point A to Point C, but it’s not depicted in the movie. Even if they said a simple line during the “transferring” of the plans to the disk someone says “Is the docked ship ready?/something on those lines” helps to bridge the logical step … audibly at least.
It’s somewhat similar to the Doctor & Ponda’s cameo (We see them in a city that then get’s destroyed … logic dictates they leave, but we don’t see them do that and just witness the utter destruction of it … so makes it more of a plot hole than not), but at least the droids are not a cheesy/shameless fan service cameo since seeing them makes sense in the story at this time.
