Modding often involves overwriting core files like the pac folders or the etc files. If a mod is incompatible, the game may crash on startup. Having verified vanilla files allows you to swap back the original data without reinstalling the entire 50GB+ game.
If you are using the Steam version of WWE 2K19, the process for securing verified vanilla files is straightforward. Steam includes a built-in feature to check your local files against the official manifest.
By maintaining verified vanilla files, you ensure that your WWE 2K19 experience remains stable, whether you are playing the game as intended or transforming it into a custom wrestling masterpiece.
