Recommended by who? Maxis doesn't have anything against mods, but they don't support/recommend them, because they obviously can't check/control them all and mods/CC can cause issues with your game. Try to repair the game on origin, that helps sometimes.Ĥ. When something is messed up, take your mods out of the game and see if the problem is still there. Before downloading, I would check the comment section if other people are having issues or not. It is safe as long as you follow all the rules above. It usually still works with new update.ģ.

However, I've never had any problems with CC. Sometimes, some mods don't work anymore and have to be updated. No, but it's recommended to take out your mod folder every time you update the game and check if your mods are still compatible with the new game version. Look in the description of the mods for any compatibility issues.Ģ. But these issues should be fixed if you remove one of the mods. There also could be some issues because some mods are not compatible with each other. It's recommended to organize your CC/mods in some way, so that it's easier to find stuff if you want to delete something. You should always test CC before you use it! I had some problems with CC not showing up correctly in game, so I had to take it out.

But it also depends on the particular mod/CC you download.

Normally, it shouldn't screw up your game if you install everything right like you're supposed to.
