UI Cheats Extension was specifically causing the most issues with the new Sims 4 version – causing a lot of weird visual glitches and misplacements in the User Interface. Unfortunately with the latest Sims 4 update many have reported weird glitches while having these mods enabled (even though we always say – disable your Mods before their new versions come out!). The first one lets you take full control of gameplay via easy shortcuts in the User Interface while the second lets you control pretty much every aspect of the game. Probably one of the two biggest mods used by the modding community are UI Cheats Extension and MC Command Center. Plenty of us in the community who play The Sims 4 on PC like the additional layer of control in Gameplay that certain Mods provide.
