Re: do cheat codes break the game?

Cheats

Most cheats which harmed you game are removed. (Self the really helpful destroy cheat!) I cheats skills traits and make happy if I test things or if I create a family for my master save.

Traits

@Sindocat is right here, its glitchy in vanilla littleMsSam have a bug Fix for this (Bug Fixes -> Trait Buff Fixes) In Vanilla don’t change your traits, self with potion it can glitch out.

Hybrids

I would recommend using the mod All-in-One Occult Hybrid Stabilizer (ModTheSims). Vanilla Hybrids don’t break your game, but they are really glitchy if they have two occults form. The Mod helps a lot with this issue. In my vanilla game I remove one occult state via flip a coin prozess.

Restaurants

Depends, if you only decorate the walls with this cheat, it should not harm your restaurant. Just have these simple Rule-Set: Not more as 5-6 Tables, 2x Kitchen, No Showkitchen (Fridge,stove). I don’t use Bars anymore because me guest used it most the time not and with bars you have one sim there which just stand there. Vanillla Game create only max 20 Visitors (if I remember this correct). Restaurants are generally very wonky, they work great (if the cook does not bug out) if you build these right.

Performance

You don’t need to quit to use moveobjects but maybe have a little less clutter. Most gallery popular houses/lots have to much clutter and its help a lot if you just remove the landscaping or as @xochiquetzl_xkvn  recommend just remove some items from your inventor.
