Patch jobs are uncommon, but not unheard of. Occassionally the roller will accidentally nick the wrapper or there may be an unnoticed hole in the wrapper, so they just patch it with a spare piece of wrapper. The veins are just likely luck of the draw. Tobacco is a natural product, and the wrapper leaves are sorted by humans, so on occasion, a slightly lower grade can sneak its way to the rolling tables. I'd say the same to your one "odd" one. Could be just the bad one of the box, or you could have just smoked it in a sick period. If it was a consistent problem throughout months I'd be worried, but one stick ain't enough for alarm in my book.
