Yes the sims 3 is a real pain to play often,I took a long time to make-peace with it,these last weeks now I'm satisfied with my ccs and the game runs awesomely, I'm glad to play with it again I created sims I adore lol.
Though I believe you and I agree with game make us crazy.
About the last patch 1.29 if I'm right, I don't advice people to apply it,due to the fear I've got concerning the CCs even though this patch is quite essential.Moreover I don't patch my game anymore since I've installed pets and I won't update it anymore.(I don't install Origin)
I'm verry sorry for you and I wish you good luck for fixing all the pain the game caused.
Chin-up sweetie !
S3 is a fantastic game, very awesome and entertaining like the sims 2, but more difficult to manage to.
