I feel your pain. I have done this more times than I like to admit. I am currently missing the first two blocks of a BOM I started getting. When I received the 3rd one, I was going to put it with the other two. I will if I can ever find them! Glad I wasn't planning on doing it them any time soon. It is nice to read that everyone does this at some time or other. But I must say the missing glasses is just weird.
