Bad racks are not uncommon with refs, if you look at the AccuStats videos or the ESPN stuff from the 80s, 90s early 2000s, the 9 ball was made quite a lot, if not made it would still go towards the corner. I would say maybe half the racks were "good". Best part was the crowd cheering the 9 going in like it was a good shot or something.
Rack your own is not a "solution" but an option that comes with it's own issues. Notable recent example, DCC 9 ball this year, Frost vs Immonen match, Frost made like 3 9 balls off the break, straight in the corner pocket. Rack your own would be better if the 9 did not count on the break. Even then, you can wire a corner ball very easily by just not fixing a gap.
