I noticed quite a few mistakes regaring continuity of Jedi robes, namely Obi-Wan's and Yoda's. Let me elaborate:
-On Utapau, Obi-Wan ditched his cloak before fighting Grievous. After he defeats him and escapes Utapau, he boards the Tantive IV, still without his robe. The next time we see him is outside the Jedi Temple, fighting clones. With his robe on. Now this was before he and Yoda entered the temple, so he couldn't have grabbed a spare robe from inside the Jedi Temple. Where did he get the cloak?
That's not all, folks.
-During the Yoda vs. Palpatine fight, Yoda also loses his robe. It falls on some sort of pipe or rod. But the next time we see Yoda, he's still without his robe, crawling around in a vent. Why didn't he take his robe? Then Bail Organa rescues him, and the next time we see Yoda on Polis Massa, he has his robe again. I highly doubt they stopped off at the Jedi Temple to pick up a spare robe for Yoda because Palpatine would have clones search there for Yoda.
The final error:
-On Mustafar, Obi-Wan throws his robe to the side when he fights Anakin. When he returms, he boards Padme's ship without his robe, so we can assume he left his robe on Mustafar. Threepio or R2 could have brought it on board, but that's highly doubtful, since they were too busy taking care of Padme. Anyway, Obi-Wan also goes around sans robe, but at the very end of the movie when he delivers Luke to the Lars family, he has the robe again (and thankfully, he keeps it on from now on). Where did he get it? I don't understand it?
Were GL and crew asleep, or did they just think people wouldn't care? I assume they thought the latter, but oddly enough, I care. Because I'm a nitpicker.
