DQuiet’s Sim Control Hub update fixes save-breaking Sim data loss

DQuiet’s Sim Control Hub just took a major step toward safer save-file management, with v1.5.2 fixing a bug that could make added selectable Sims lose relationship bits and persisted data after changing zones. The repair targets an incorrect LOD assignment that treated those Sims like low-priority background data, a problem DQuiet says could quietly snowball into long-term save weirdness.

In a May 24 devlog, DQuiet said the issue showed up when a Sim was removed from selectable status. Instead of being left in the right state for active use, the game had been setting that Sim’s LOD to SimInfoLODLevel.BACKGROUND. The fix changes that to SimInfoLODLevel.INTERACTED, and DQuiet said it should make the mod “significantly more stable overall.” DQuiet also credited lychee with reporting the problem, a reminder that small community bug reports can prevent big household headaches later.

The same update folded in v1.5.1 changes dated May 22, including a new option to display Sim Control Hub interactions as their own main pie-menu category instead of leaving everything under Actions. For players juggling large households, rotational saves, or heavily customized playthroughs, that is more than a cosmetic tweak. It puts the mod’s tools where they are easier to reach, especially when you need to move fast between Sims, lots, and situations.

That control layer now goes deeper than menu placement. The update added management interactions for selectable Sims while they are sleeping, a check that prevents Household NPCs from starting Discovery Quests, and a fix for the Allow Pet Control option so it remembers its saved state across game restarts. Discovery Quests were added in a free October 31, 2023 update and act as tutorial-style tasks that reward money and satisfaction points, so blocking household NPCs from triggering them helps keep the mod’s control systems from colliding with the game’s own guidance.

Sim Control Hub’s broader feature set makes the appeal clear. The mod can add and remove selectable Sims, manage travel groups, start Stay Overs, handle situations, and release occupied zones when a group ends. DQuiet’s feature overview says it can be accessed through the pie menu, hidden in Shift+Click, or used through the Relationship Panel. Once a Sim is added from Actions > Sim Control Hub, that Sim can be controlled like a playable, including changing outfits, managing needs, and sending them to work.

That systems-first approach has been building for a while. A May 16 preview version added interactions that let active-household Sims become autonomous NPCs and expanded Bring Here to support special NPC Sims such as Fia Acosta, a character tied to Electronic Arts’ Royalty & Legacy material. With v1.5.2, the mod pushes harder on the same goal: fewer save-breaking surprises, more direct household control, and a cleaner way to keep a complex Sims 4 setup stable.
