Important! Sims 4 cas.fulleditmode bug
If you have the new Sims 4 EP Growing Together, you need to know that there's a bug with cas.fulleditmode and Sims with added traits (beyond the basic 3 traits). If you trigger this bug, all your household Sims will have the same name and your CAS UI will be corrupted. Worse, this bug can spread to other Saves.
You can avoid this bug:
- Back up your saves outside the game folder before you play. Make this a habit. Don't rely on an automated online backup (like Drive) to do this; there are known issues with this.
- Save before entering cas.fulleditmode. That way, when you do the next thing, you haven't lost a lot of gameplay. You might be fine if you're not touching Traits in CAS, but play safe!
- If you encounter the bug in CAS, exit without saving.
- Before you open a new save, exit and restart the start.
There is not a mod for this bug. When this bug is resolved, I'll updated this post.
