With all due respect, it was known for quite a while now that the main point of this update was reworking the base code. That way it wouldnt be necesary to rework bits of it every single update (Precisely what you're complaining about!!). It was also known that neither saves wouldnt work, nor we would get an impressive amount of content bc of this. This update was code related first and foremost.
Please understand that a game in continuous development will experience, well, changes; both in content and story, as well as in the code itself. Just like every other project. Hardly anything to be surprised/dissapointed about.
Moreover. The game includes a save where you can access the reworked content inmediately, so im not sure what the main problem is, given that you dont HAVE to play everything all over again. Not only that, as of right now there are people in the community working their asses off to provide with full saves as quickly as possible.
