They fixed it almost all the bugs + annoying features. Sims will still sniffing but the idle got a cooldown before it plays again. So, it’s much better now.
The only issue I still get sometime is this: https://answers.ea.com/t5/Bug-Reports/OPEN-BDK-Showing-Clean-and-Dusty-moodlets-Simultaneously/td-p/11795085
It’s only the moodlet dust will still occur normal and after it gets light dusty the double moodlet gets away. It personally doesn’t bother me.
Off the Grid doesn’t work because of this bug: https://answers.ea.com/t5/Bug-Reports/OPEN-BDK-Vacuums-Don-t-Work-Off-The-Grid/td-p/10143621
I upgraded it and still couldn’t vacuuming, so you need Eco Living and a source of power generator. (I checked it in my vanilla game and is still bugged)
Dust occurs normal for me. If you have more sims dust will occurs faster as example a family from 5 with 2 pets got dust each 2-3 days. I personally don’t had any issue with vacuuming but I play in houses which are for gameplay and don’t use MOO(MoveObject). Light use of MOO should not cause any issue. So more MOO you use so likely you get routing issue for vacuuming. If you have a Maid or a Butler, they should vacuum automatic. // Robot vacuum from Cats & Dogs works too for cleaning.
All in one I think its now in a state which its worth the money, specially if you on PC you got a ton of mods which you can tweak feature (Example: No Dust-Bunny, no moodlet, no Idle, no clean sparkling, working broom for of the grid and more)
