I've just installed the Sims World Adventures and

now my Sims cannot communicate in any form.
What can I do? Is this a bug?

edit- I've tried running the game without custom content, it didn't work. Or do I have to remove it from the Mods folder?
I did not patch my game.

edit-I reinstalled Sims 3 and also the expansion pack. This time there was no cc or my saved game. When I played, there was only mean interaction and when I got them on the bed to woohoo, they sort of jumped of the bed and into another room like teleportation. Then I had the same problem again, they couldn't communicate.

Have you removed all your CC?  I recall something about an 'ask if single friendly' mod borking some kinds of communications.

Have you patched your game?

You don't have to delete all of your CC.

To remove CC it doesn't mean DELETE forever. Move it to your desktop. It's a good idea to place CC completely out, to see if the problem exists because of it. Disabling CC from the launcher or whatever options it might have won't work for things in mods folder only installed with the launcher. Clear cache files before loading up and start a new hood. Your old hood/sims might be corrupt if you used a incompatible mod with a pre WA save.
