I regret buying Eco Lifestyle. This was the first pack I bought within 24 hours of release, and I shouldn't have. I had to roll back to an earlier save due to the NAP spam gumming up my worlds (at least I had that backup though). I turned off NPC voting on the spammy NAPs so my current save is safe from this, but I'm really unhappy that I can't use features in the pack that I paid for. Plus I have many of the other issues posted at the Bug Reports Forum at AHQ. My plants are messed up, sims motives drop at a weird rate, the eco foot print seems broken, etc. and so on. I'm really unhappy at how much these bugs have stuffed up my game, 6 weeks and no patch for them, and minimal communication regarding them.
I'll never buy a pack at release ever again. I refuse to buy any future packs no matter how much I like them until they fix these bugs.
