I find many mistakes with lego each year, and this is for star wars only.
1. On the fixed wing of the landing craft, where it is white is supposed to be gray and where it is gray it is supposed to be white. (maybe they did not have gray slope bricks)
2.On the summer issue of 2006 and on pages with Jabba's sail barge, you could see the reflection of the bottom too.
3.On some catalogs and magazines, it says that the isd's meditation chamber is the command center.
4. Also, it shows pics from the death star, instead of isd pics.
5. The meditation chamber is only in the Executor, I believe, and not on ISDs.
6. The landing craft says that stormtroopers wearing orange cloths are sandtroopers but the ones in Mos Eisley Cantina are sandtroopers because of their backpacks. The orange cloth means squad leader, if I am correct.
7. The red guards in the magneet packs have black hands., also in the Celebration 4 vader box.
8. The old set with palpatine and vader and another shows black hands on the box, but yellow hands included, or vise versa.
9.Grievous' ship[ is supposed to have have proton bombs but I guess lightsabers double as that.
10. The scimitar doesn't have rockets.
11. The missiles on the y-wing are in the wrong plce, and same for x-wing that doesn't even have torpedoes.
12. In the isd issue of the magazine last year, it said that the death star was fired inly once, but I believe it was twicw, to blow up the planet over which it was constructed? Maybe that was the prototype.
13. Summer issue of last year's catalog, on one edition it said over 60 new items and on another version it said over 45 new items and the content was different.
