Queue Guard: Stop Stuck Sims & Fix Autonomy Loops

Queue Guard

Every Simmer knows the frustration: your Sim is supposed to be making dinner, but instead they stand in the kitchen twitching, their action queue filling and emptying in a frantic, broken loop. This isn't just an annoyance; it's a performance killer that can freeze entire lots. Queue Guard is a pure script mod designed to detect this exact failure pattern and correct it in real time, giving you back smooth, logical gameplay.

Why Do Sims Get Stuck in Autonomy Loops?

Before diving into the fix, it helps to understand the problem. The Sims 4 autonomy system is complex, and sometimes it misfires. A Sim will repeatedly queue the same autonomous interaction for several reasons:

• Poor tuning: A specific object or interaction has broken animation data that fails to complete.
• Unreachable targets: The Sim wants to use an object that is blocked by clutter, walls, or routing failures.
• Hidden mod conflicts: Even mods that don't directly edit the same files can cause subtle logic errors in autonomy decisions.

When this happens, the Sim appears visually stuck, their needs decay, and the game's performance stutters as it tries to process the same failed action over and over.

How Queue Guard Works

Queue Guard acts like a vigilant watchdog for your Sims' behavior. It monitors every autonomous interaction pushed to a Sim's queue. When it detects the same action being chosen 5 times within 10 in-game minutes, it steps in with a three-part correction:

1. Stops the loop: It immediately halts autonomy from selecting that specific interaction again.
2. Clears the clutter: It removes the duplicate copies of that action already piled up in the Sim's queue.
3. Implements a cooldown: It blocks the interaction from being autonomously chosen for 15 in-game minutes.

Once the block expires, the interaction is allowed back into the autonomy pool. If the underlying issue persists and the spam starts again, Queue Guard re-blocks the loop for twice as long as the previous block, up to a maximum of 4 in-game hours. This exponential backoff ensures the mod is aggressive enough to stop persistent problems without permanently disabling content.

Diagnostic Features for Advanced Users

Queue Guard isn't just a fixer; it's a detective. Every correction it makes is silently written to a log file in your The Sims 4 user folder. This log is invaluable for identifying which specific interactions or objects are causing the trouble, helping you pinpoint broken CC or mod conflicts. If you prefer visual feedback, open the cheat console and type queueguard notify to enable in-game pop-up notifications for each correction. Note that since this is a pure script mod, all notifications and log entries are in English only.

What Problems Does Queue Guard Solve?

This mod is a lifesaver for players who experience any of the following:

• Autonomy "thrashing": The endless, rapid-fire queueing of a failed action that leaves Sims looking like they are having a glitchy seizure.
• Performance stutter: FPS drops and lag on busy lots. This is especially noticeable at festivals, in apartments, during club gatherings, with full households, and in packed venues like nightclubs or gyms.
• Frozen or stuck Sims: The dreaded state where a Sim stands idle, completely unresponsive to player commands because their queue is jammed with invisible, repeating actions.

By eliminating these loops, Queue Guard keeps your game running smoothly and your Sims acting like actual people instead of broken robots.

Compatibility and Installation

One of the best features of Queue Guard is its compatibility. Because it is a pure script mod, it does not alter any game tuning files or XML data. This means it will not conflict with other mods. It is fully compatible with popular mods like Simulation Timeline Unclogger and Interaction Queue Extender. Furthermore, it is base game compatible, meaning it works with all versions of The Sims 4, from the base game to the latest expansion and game packs, without needing updates for every patch.

For players looking to streamline their mod setup, the foxygame.net launcher offers a one-click install for Queue Guard, automatically placing it in the correct Mods folder and verifying version compatibility with your current game build. This eliminates the manual hassle of downloading and extracting files, letting you get back to playing faster.
