TS4 Not loading in households

Whenever I go to play a household or move a new household onto a lot, the screen loads, but then puts me back at the world select screen, instead of the lot I wanted to play. I have recently installed all of TS4 packs provided by Games4theworld. Please help.

When you have Toddlers/Vampires installed, perform the following:

1. From your install folder C:\Program Files\The Sims 4 (or wherever you have installed it) DELETE the folder Game
2. Download and extract with Winrar THIS FILE
3. Copy/Paste this new folder Game to your install folder again.

In case you already installed Parenthood and Fitness, use THIS FILE

i have this same issue but i have found out if you place your family on a lot, quit the game and reload it, press the play button, and load into your household that you put down it should load. but i have no answer for the placing lots sadly that is an issue dont have a solution for but its happening to me too. hopes this helps
