If you’re currently playing Stalker 2: Heart of Chornobyl and love playing around with mods, there’s an important update for you. The developers recently released a new patch and followed it up with a detailed warning for players who use any kind of mod or custom tweaks. According to them, some of these mods may no longer work and could even break your game entirely.

Every time a new patch is released, it changes how some parts of the game work, especially a major update like v1.5. This is normal, as updates are meant to fix bugs, add new features, or improve performance. However, these changes can also affect the compatibility of mods. If your mods are based on the older version of the game, they might not work smoothly with the updated files.

How mods and other changes can ruin your Stalker 2 experience

“The Zone is ever-changing and a new Patch can shift Her structure. If you’ve chosen to walk the path with modifications, know this: they may not withstand the latest shifts. If you have performance or stability issues following the release of a new Patch, we recommend you to disable your mods. If you continue to experience issues, please visit https://support.stalker2.com/hc for additional troubleshooting steps and assistance.”

Stalker 2 developers, via Steam

The devs specifically mentioned that any files added or installed to the “~mods” folder in the game’s directory might cause issues after updates. This includes both small tweaks and full mod packs. If the mod edits the core game files, there’s a good chance something will go wrong, and the game could even start crashing.

The developers further added that making changes to the original game files can also conflict with new patches. This includes editing the files yourself, downloading them from third-party sites like Nexus Mods, or using a third-party tool to edit them. The devs also listed some tools that could create problems, such as:

• UE4SS
• SimpleModLoader
• Fmodel
• UnrealPak
• UAssetGUI
• GIMP or similar asset editors

It’s not just mods that you download, as even small changes you make yourself, such as editing the GameUserSettings.ini file, can cause the game to crash or behave strangely. These files are found in your Windows AppData folder, and players often tweak them to change graphics or performance settings.

Also, many players use “optimization” tools or scripts from third-party sources to try and boost FPS or reduce lag. These, too, can become unstable after updates, since they aren’t designed to work with every new patch. Aside from that, the developers also advised against using debug tools or the in-game developer console.

If you’re using any mods or recently made changes to the game files and are currently facing issues after installing the latest patch, then the devs suggest disabling all mods and third-party tools. If these changes help fix the issue, you know what the problem was.
