I wanted to start a new Every Expansion Pack Challenge in the new Sunlit Tides world but for that I needed to place all the lots that came with every expansion pack, so I made a save game that has every standard expansion pack lot in it. As I have already done the work, figured I might as well share it with you all!
You can find the download here:
Sunlit Tides with all the expansion pack lots
You extract the Sunlit Tides-All EPs.sims3 folder to your documents\Electronic Arts\The Sims 3\Saves folder, then when you load the game you will have another savegame called Sunlit Tides-All EPs.
Note: if you have the new the Serenity Retreat venue you do have to place this yourself, there is a great spot for it near the ocean and Pleasants house.
