Insufficient randomness from random.org?
Odd. Seems like the only way it wouldn't be random is if the code transforming the output into die rolls was wrong, or if the inherent unfairness of dice with pips carved out of them is truly desired (which, it seems, could still be modeled from a truly random source).
A cool machine though. I was expecting the captures to take place somewhere other than the lifting chain though, but it makes sense for the setup.
