That's just how game development works nowadays, it's not exclusive to western CRPGs though it might be more prominent in them.

Truth is games have gotten extremely robust and complex aince the days of Doom. Instead of 100s of interactions games now have dozens of thousands and all of them come with the possibility of a bug or multiple bugs.

It is unfeasable to expect them all to be found and ironed out at release. That would take thousands of QA testers and months of testing after the game has gone gold, which is just a roundabout way of doing Early Access.

You have also to keep in mind the shift from games being made from a "one-and-done" perspective to a "live-service/continued support" one. The fact that devs update and patch their games is actually a good thing overall. The other option would be they just abandon them and that'd be it.
