This likely happened because when they wrote the RNG they only checked the long term result -- run the code a thousand times and see how many times each number comes up, and if it approximates to 1/20 to each number call it a success. But you also need to examine the spread of each number throughout the 1000 rolls to make sure they don't cluster together in a way that a good RNG shouldn't.
How the hell could they screw this up so badly? Are their devs more incompetent than others who have made d20 based video games or even the tiny teams making VTTs like Fantasy Grounds? People have been successfully simulating d20 rolls using computers for decades.
