Hello, I have sims 3 late night installed updated to the latest patch. I have awesome mod only installed on the Mod/Package folder. Once I started the game using .exe then blackscreen and a popup it says "It looks like you have installed an unofficial game modification that does not match your current version of The Sims 3" and so on.. I pressed continue then the game loads then a popup again "Non-Critical core mismatch" warning appears I clicked ignore, then I started a new game to test if the mod will work. Once I enter the house I can't command my sims they're just standing. I command them to walk or change outfit but they are just standing moving their hands.
