ECO Living is Complete Garbage

So sorry you are having so many issues. Last year at this time, I was in your shoes after the Island Living update threw my game into total chaos for months. I had so many issues, I stopped counting. I haunted the help section on a daily basis, and thought i would never get my game back. It was the first time any update or pack had totally derailed my game, so I was beyond upset. But I did finally regain control after a lot of trial and error with mod fixes, a complete uninstall and install, maybe hundreds of repairs, loading only certain packs, playing without CC or mods. One day it all finally clicked, and my game was fine. To this day I have no idea what was wrong. It just happened out of the blue. I understand your frustration because I've been in your shoes. But don't give up just yet on EL. If you use mods or CC, pull that folder out and do a repair then see if doing that helps with the lag. You could have a mod or piece of CC that needs updating. Make sure your graphics card is updated. Try a lag fix mod because sometimes using a mod is the only solution when we run out of ideas about what could be wrong, or how to fix it. At one time, I was using over fifty bug fixing mods and forty mods to nuke all the autonomous actions that irked me. Thankfully, that number has gone down to ten bug fixes, and thirteen irritation nukers in the past few months. I know it feels as if your game will never get better, and you're frustrated. But sometimes we have to find our own fixes for bugs and issues because everyone's PC is different. And the fixes from Maxis don't always work the same for everyone.
