I have 3 Tie Fighters, set #7146
. Each one included one of part 30000: http://www.peeron.com/inv/parts/30000
on which one stud has LEGO printed on it in the opposite direction as the other three. these are the only pieces I've seen with the imprint not all the same direction. The three other parts like these in each set were normal.
I have 2 of set #7566
Farmer. The head in one set does not have holes inside the stud, but the head in the other copy does have the holes like most other heads made recently. Both were bought at the same Kroger store.
Anyone else notice any oddly made pieces in their collection?
