I'm setting up a new save file in a version of Sunset Valley and wanted to share the version of SV I'm using:
Sunset Island 2 ~ From the Sims 3 Exchange (uploaded in 2013)
https://www.thesims3.com/assetDetail.html?assetId=7776648It's features:- Original Sunset Valley.
- With all Original Townie Families in their homes.
- Edited in CAW to smooth out the land, roads and routing (as far as I can tell)
- Has all expansion pack community lots except for WA lots and University lots.
- Has all dive spots, some house boats, docks and a hidden island.
- Has several empty lots to add store lots/venues.
- No Resort, but can be added.
Packs Used: WA, Amb, LN, Gen, Pets, ST, SN, IP and ITF
If any of these packs aren't installed, their lots will still show, but will not function.

I've known about this version of Sunset Valley for a few months now, but haven't taken a good look at it until a couple weeks ago.
The only problem I see that might cause issues are the lots on Pinochle Point. Some of them towards the end of the road seem to be slightly elevated or have a slight dip to them. Making them iffy to build on and may cause terrain issues with the lot.
This version isn't be supported anymore. The main support site is not up anymore, so I don't think anything will be fixed or updated. I don't know enough about CAW to fix it.
