I think it was 5th Edition D&D where the original release date for the DMG had to be delayed when they got the first print run and an entire chapter was somehow 'Lorem Ipsum'. Major printing errors happen. I would prefer FFG to come out and mention something about the delay, but they have to be extremely frustrated with whatever happened. I will continue to eagerly await both books. Considering they just posted another article on Fully Operational, I suspect there's some movement there.
