Lol I installed World Adventures and took out AwesomeMod so I could play it, the only only only only problem I have encountered is when I tell my sim who is a writer to write a new book, he will just stand by the computer, and the thing from the que will disappear. That is the single problem I have found. Yay for me!
I had that after the 1.6 patch autoinstalled, I removed all the make x more fun hacks I had in and it cleared it so check if you have anything like that installed still. WA was not released in the UK until the 20th but I never bother installing an expansion until Pes has had time to do his thing and fix whatever EA has broken, I'm happy to wait for as long as it takes him, it's just easier and safer that way!
