Broken Witcher 3 mods explained

The Witcher 3 is an undeniably beautiful game. However, CD Projekt Red has released an update that improves the game even further. Moreover, in this update, they used several community-made mods.

And although it improved the game, many players have encountered Mods being broken due to the update changing many of the game's files. As a result, many Mods that were used to modify these files just broke when the update released. It is very frustrating for players, as many of them like to play with various mods, but fortunately, there are ways you can fix this.

How to fix broken mods in The Witcher 3

If you want to play your favourite action RPG with mods, you need to download Script Merger. It is a Mod created by AnotherSymbiote to find and resolve Mod conflicts in text files.

All you have to do is go to Nexus Mods and download Script Merger. Then run the application and enter the path to the folder with the game installed. Now you can start fixing Mods.

Click the refresh button to find all conflicting files in the game. Then, select all versions of these files and click Create Selected Merge. Script Merger uses KDiff3 to merge files. Therefore, in most cases, this tool will automatically merge selected versions of files. However, if Mods have overlay changes, you will need to merge them with KDiff3 manually.

Also, if Script Merger finds conflicts between non-text files, it cannot merge them. However, it will still display those conflicts. In this case, only one of the Mods will work and override the rest. To change the working mod, you must right-click on it and set the priority from one to 9999. If you do nothing, then The Witcher 3 will launch the Mod standing first in order (numbers, underscores, letters).

Also, there is a second way to fix broken mods. And, of course, it is uninstalling them. We recommend that you only uninstall mods that cause conflicts but cannot be fixed via Script Merger.

That's all you need to know about how to fix Witcher 3 broken mods. The new update made the game better in terms of performance and graphics, but worse for mod users.
