Re: The Sims 3 Mods aren't working for me...
@draabiczek It looks like you have everything set up correctly. (I take it you've downloaded the Sims 3 version of the hair in your screenshot, not the original Sims 4 version.) Do the NoIntro and NoBuildSparkles mods work with no other mods added? It's worth testing just in case there's a problem with one or more of the .package files you're adding.
If those two mods alone don't work, please open a File Explorer window, click This PC, and enter "deviceconfig" without quotes in the search box in the upper right corner. Please let me know the file path of each copy you find, as well as the date modified on each one. It's possible the game is using a different Sims 3 folder for some reason.
