I’m sorry, I’m not sure I understand your question? Sim Updates have always been about bug fixing (a couple that’s all they were), and adding sim functionality. World Updates have always been scenery updates.
If you’re wondering why they chose the bugs they are fixing vs the ones you want fixed… sorry. Be assured they have reasons that make sense to them. Also be assured many bugs will be fixed. Sadly, they can’t fix all of them at once. You can see the release notes of what they’re doing in the Beta forum and the Devsupport forum.
