Just wanted to bring this to your attention.
It may be have been a couple of bad joints. It does happen from time to time as with anything where there is human hands involved there can be human error. I wouldn't think it is something you will see often. I am sure PMRGirl will comment as well on the problem; sorry you had problems.
