There are 2 things I never understood:
1) Where did the Eopies go in ANH? Did they all disapear at the same time?
2) Difficult to explain in English:
On Tatooine: "This R2-unit has a bad motivator, look!" Why does he say that? It is clearly an R5 unit (R5-D4), you can see it at the 'head' of the unit.
I asked that a while ago to the JediCouncil @starwars.com but they didn't answered. 😕 😕
