✽ ~ Updated Mar.2023✽ -- ✽ Edited the .world install path for fixed worlds. Example, Twinbrook (Ambitions)
When you see a world that you like, such as the fixed Twinbrook world -
http://modthesims.info/download.php?t=4562201.) Download all the zipped files for the world.
2.) Once all files are downloaded, rename the files if necessary.
3.) Right-click on the first file and select Extract Here from the menu.
4.) You should now have a file called Twinbrook.world.
5.) Right-click on the .world file and select Copy from the menu.
6.) Navigate to the world's folder - C:\Program Files\EA Games\The Sims 3\Ambitions\GameData\Shared\NonPackaged\Worlds
7.) Rename the original Twinbrook.world file to something like Twinbrook.world.original. (this is okay to do - it won't hurt the world)
8.) Right-click and Paste the new file into the same folder.
9.) Before launching the game, clear the game cache.
