Streamlining Lot Challenges ft. DLCs

I'm excited about the new Lot Challenges. I'm also excited that the Lot Traits panel, which includes both base game and DLC lot traits, will be reorganized alongside this update. The following are some of my ideas on Lot Challenges that incorporate gameplay features from previous packs, which are not necessarily lot traits but fit well with the concept of the upcoming mechanic.

Laundry Day
from Laundry Day Stuff Pack
- This Lot Challenge enables the laundry system for this lot. Go ahead and get the hampers and washtubs ready!

One of my minor pet peeves is that I can't place hampers and washing machines purely for decoration purposes because trying to do so automatically enables the laundry gameplay. With this new Lot Challenge, doing laundry activities is optional, and we're free to use the BB objects. On the other hand, we can also play with the system without the necessary appliances and objects (but with the pack, of course) and just watch our Sims swim in piles of dirty clothes, lol.

Bust the Dust
from Bust the Dust Kit
- This Lot Challenge enables the accumulation of dust and the dust system for this lot. Now stretch those muscles 'cause we'll be vacuumin'.

The option in the Settings looks so out of place, lmao. Also, in rotational gameplay, there are some households we don't want the dust system on, and some we do. I think it's cool if the setting is lot-specific rather than per-save.

Vampire Invasion
from Vampires Pack
- Missed Vlad missing your Sims' neck? This Lot Challenge enables vampire invasion for this lot.

I haven't gotten this for a very long time, I swear, and I really want it to spice up my gameplay. And to shush those who say that it is "too intrusive," we have this Lot Challenge for objectively enabling/disabling this feature. Plus, I think this option's better and more straightforward than the one hidden in the front door options.

How about you, guys? What are your ideas?
