The game is completely broke. It's nice that they managed to break more things than fix them last patch. At the moment you cannot develop crusade normally because you don't get experience other than logistics, which means that you are blocked with edicts. Luckily, you can edit save to fix it somehow, but it's still annoying.
Completely broke is hyperbole. People have finished it, so it is not completely broken. You have some other valid points, but exaggerating like this really lowers the weight of your arguments in my opinion. I recognize that this is how people talk on the internet, but that doesn't make it an effective and useful communication strategy.
