I don't mean to be a contrarian or an apologist about this but honestly, what were you expecting?
Like, this happens literally every single time Paradox release any update or expansion. After forty hours with hands on, we all decide that it's "literally unplayable" and sulk about it. Every single time. And in this case the team have, in the space of like four or five months, overhauled the entire economic system of the game and softened up a significant proportion of the hardcoding. Maybe they bit off more than they could chew in the time they had? Probably. At least they aren't resting on their laurels.
It has been pretty clear from the dev diaries that this one is coming out of the oven still raw. There were features shown in diaries that were being changed entirely by slightly later diaries. Like, they were showing this stuff off when it was still in the early design phase, let alone implementation. To be released in three months time. It probably released now so that people can get it before Christmas but also there's enough time for a support patch.
And the economy changes. Adding a whole layer of economy in the form of finished goods that are necessary to keep afloat. I've seen LPers drowning in raw resources that they simply can't use, lacking the building slots necessary to build the needed factories to turn them into the vital consumer goods and alloys. To say nothing of housing and amenities and crime. I have no idea if I'm gonna be able to work this economy (because it sounds like it needs a serious balance pass) let alone whether the AI is somehow gonna be able to juggle all these additional balls, when before it couldn't even figure out that it needed food. It's now a lot more difficult than just building the appropriate building on resource tiles to run a healthy surplus of everything based on that, and then filling empty tiles with mines. I'm not at all shocked that the AI isn't set up to deal with it.
In summary, if you're still shocked by a Paradox expansion being borked on release, then you're a wingus.
If you're shocked about an update with an overhaul this deep being borked on release, then you're a dingus.
There'll be a beta patch in a week and an actual patch in a month. Until then, just report the plentiful bugs as patiently as you can. And please do be patient. Raging and cussing doesn't get it fixed any faster. It just makes the people whose job it is to fix it a little more sad.
