Had the same problem. I have several mods loaded. As soon as I enabled hearthfire and entered breezehome, I would crash to desktop CTD. I downloaded and installed BOSS, got rid of about 10 mods that had warnings. reload, enter breezehome, crash. I disabled the lighting mod mentioned earlier in this thread, reloaded, entered breezehome, crash. I decided to go to dragonsreach, buy the childs room upgrade and see what would happen. I did so, and leaving dragonsreach, the game crashed. I reloaded again, this time figuring I would consider breezehome quarantined and just not go there anymore, and to my surprise (after hitting 'continue' from the load screen - not loading a particular save), the game loaded outside of dragonsreach. I walked down to breezehome and walked right in. I left, entered, etc. no issues. While this effort was a complete pain in the butt to resolve, I learned how BOSS worked and would STRONGLY recommend taking the time to get it and learn how to use it. My overall game play has dramatically improved. Graphics are better, more responsive, game is smoother. I am disappointed I waited this long to try and figure the CTD problem out. I was worried I would have to restart my game to overcome the CTD problem with Hearthfire - now I'm debating restarting as the game is so much more playable than it was before I cleaned up (removed/deleted) the bad mods with BOSS.
