Don't let the last poster scare you away from CC. Yes, there were problems with a few items after the Cats & Dogs patch but, there was a simple to use batch fix available from Sims 4 Studio within 24 hours that cured the problem for all the affected CC. It's also not fair to say the script Mods never break. MC Command Center needed to be updated and re-installed after the Cats & Dog's patch. If you ever have problems with CC/Mods just ask for help here on the forum. We are a pretty supportive group! It is also good to monitor the Mods Bugs and Game Issues master thread. If something breaks after a patch, there will be information there on what is broken and how to fix it.
