For what it’s worth, $75k and whatever time you spend on this doesn’t seem like a massive amount. I feel like you took a risk when you had many other things to do and the risk was calculated and overall worth it — even if you got unlucky.
It could be worse. I’ve never lost any sleep because of it. Regulators have the best of intentions in California so far as I can tell, so just a few hoops to jump through.
