If you’ve been grinding your underground empire since Early Access launched, you likely hit a frustrating progression wall. The scam center simulator scam sticker bug fix is finally live via Hotfix v0.1, resolving the critical issue that prevented players from unlocking the essential sticker mission. This quick troubleshooting guide explains exactly how to force the update on Steam, verify your game files, and get your illicit operations back on track so you can focus on dodging police pressure and paying off your debt.
When solo developer Wendy launched Scam Center Simulator: UnderKingdom on May 29, 2026, the game immediately drew thousands of players eager to build a criminal empire. But a severe logic error in the launch build halted the main campaign dead in its tracks.
Why You Need the Scam Center Simulator Scam Sticker Bug Fix
After 1.5 years of development, the Early Access release of Scam Center Simulator: UnderKingdom delivered a deep, punishing management loop. You recruit workers through shady means, manage facility upgrades, and literally turn your workforce’s labor into electricity to keep the servers running. However, players quickly discovered that the mid-game progression was completely broken.
The bottleneck occurs during the Jiao questline. Jiao tasks you with expanding your fraudulent operations by deploying a "scam sticker" to automate passive income. In the initial May 29 Release, the trigger for this mission failed to fire. No matter how much money you made or how many rival gangs you paid off, the mission remained locked.
Without the sticker mission, your automation is crippled. You are forced to manually collect revenue from every terminal, which spikes your police pressure and leaves you vulnerable to constant raids. Hotfix v0.1 (Build 23470603) specifically addresses this script failure. Applying the patch is non-negotiable if you want to experience the late-game content, upgrade your facilities, and survive the escalating chaos of the underground city.
Step-by-Step: Forcing the Scam Center Simulator Scam Sticker Bug Fix on Steam
Because Steam’s auto-updater can sometimes lag behind developer hotfixes, many players are still running the broken launch build. You need to manually force the Steam client to fetch the latest depot data.
Here is the exact process to ensure you are running the patched version of the game:
- Restart Steam Client: Close Steam entirely from your system tray. A fresh boot forces the client to ping the SteamDB servers for new manifest IDs.
- Right-Click Game in Library: Locate Scam Center Simulator: UnderKingdom in your library, right-click, and select Properties.
- Select Properties & Updates: Navigate to the Updates tab and ensure "Always keep this game updated" is selected.
- Verify Integrity of Game Files: Go to the Installed Files tab and click "Verify integrity of game files." This forces Steam to cross-reference your local files with Depot 3484851.
- Confirm Build Number: Once the download completes, launch the game and check the bottom right corner of the main menu. You must see Build 23470603 (or higher) to confirm the fix is active.
Version Comparison: Which Build Do You Need?
| Build ID | Release Date | Key Changes |
|---|---|---|
| Launch Build | May 29, 2026 | Base Early Access release. Jiao questline broken. |
| Build 23470603 | May 29, 2026 | Hotfix v0.1. Fixed scam sticker mission unlock. |
| Build 23481179 | May 30, 2026 | Improved scam sticker behaviour. Fixed infinite raid respawn loop. |
If you are serious about optimizing your empire, you actually want to ensure you have Build 23481179, which dropped a day after the initial hotfix to refine the sticker's passive behavior.
What the Scam Center Simulator Scam Sticker Bug Fix Actually Changes
Applying the patch does more than just flip a quest flag. It fundamentally repairs the mid-game economy and fixes several interconnected systems that were breaking under the weight of the bug.
Prior to the patch, players attempting to bypass the locked mission found their worker capacity permanently occupied after exchanging favors with The Mayor. The Mayor requires a bribe to reduce police pressure, but because the sticker mission was stalled, the game never released the allocated workers back into your pool. This meant your power generation plummeted, causing facility-wide blackouts.
The update also rectifies the Street Cleaner behavior. In the broken build, the Street Cleaner would path erratically around your bunker location, failing to dispose of evidence because the automation triggers were tied to the locked sticker mission. By fixing the mission unlock, the Street Cleaner now reliably lowers your heat multiplier.
Finally, Build 23481179 stops raids from infinitely respawning. Before the fix, the stalled quest state caused the game's threat director to assume you were hoarding illegal assets without progressing the story, triggering back-to-back police raids that would inevitably wipe out your operation.
Troubleshooting: If the Scam Center Simulator Scam Sticker Bug Fix Doesn't Work
Some players report that even after updating to Build 23470603 or Build 23481179, the mission remains locked. If you are staring at Error 0.1 on your in-game terminal, your save file may be corrupted by the previous build's logic loop.
If the mission won't unlock on a patched client, you need to manually reset the quest state. Head to the central command terminal in your bunker. Instead of interacting with the primary monitor, access the secondary ledger where you manage your debt payments. Pay down at least $1,000 of your starting debt, then sleep for one in-game cycle. When you wake up, Jiao should call your burner phone, officially initiating the sticker mission.
If you are still downloading Wendy's patch and it hangs at 99%, clear your Steam download cache. Go to Steam > Settings > Downloads > Clear Cache. This will log you out, but upon logging back in, the depot will unpack correctly, and your empire expanding can resume without further technical blockers. For persistent issues, the developer is highly active in the official Discord and QQ groups, often requesting corrupted save files to patch edge cases.
Frequently Asked Questions (FAQ)
Does the hotfix delete my Early Access save? No. Hotfix v0.1 is save-compatible. However, if your save was generated on the launch build and you already triggered the Jiao conversation without receiving the mission, you may need to sleep for one in-game cycle to force the quest to update.
How do I check my current build number? You can view your active build number in two places: the bottom right corner of the game's main menu, or by right-clicking the game in Steam, selecting Properties, navigating to the Updates tab, and checking the "App ID" and "Build ID" fields.
Why are raids still respawning after the sticker fix? If you only downloaded the May 29 hotfix (Build 23470603), you only fixed the mission unlock. You must update to the May 30 patch (Build 23481179) to apply the fix for the infinite raid respawn loop.
