I’ve had two models in the past year have quality defects. In one, the parts weren’t of the right tolerance and it added a flex to the build that caused parts to pop off after a few hours. I’m the second I bought a set that straight up didn’t have multiple bags of parts necessary. I am however, not sure that it’s entirely a cost saving measure as LEGO sent me a replacement kit no questions asked in both situations. It seems more like they are switching manufacturing techniques and working out the kinks, or I would have expected needing to provide some sort of proof of the issue
