How to Fix Baldur's Gate 3 Data Mismatch Error?

If you find yourself grappling with the vexing Baldur's Gate 3 data mismatch error, rest assured that the following remedies can help restore your gameplay experience to its intended harmony. Take heed of the following solutions to address the issue effectively:

Fix 1: Discard Installed Mods

Outdated or lingering mods often take the spotlight as the chief instigators of the data mismatch error in BG3. If you've ventured into the realm of mods previously, these lingering entities can disrupt the game's equilibrium upon launch. To neutralize their impact, it's recommended to purge your system of these mods, as outlined below:

  1. Navigate to the address bar in Windows File Explorer and input: %LocalAppData%/LarianStudios/Launcher/Cache.
  2. If the designated folder exists, delete it by employing your keyboard's delete key. In the absence of this folder, follow the path: …/Baldurs Gate 3/Data.
  3. Optionally, erase the mod settings.lsx file from the profile folder to completely eliminate unsupported mods.
  4. Empty your recycling bin to fully expunge these elements.
  5. Restart Baldur’s Gate 3 to evaluate the resolution of the data mismatch error.

Fix 2: Validate Steam Game Files

For those yet to embark on the path of verifying their Steam game files, these sequential steps should guide you in rectifying the issue:

  1. Initiate Steam and locate the game within your Library.
  2. Right-click on the game title and select Properties.
  3. Navigate to the Local Files tab.
  4. Opt for "Verify Integrity of Game Files."
  5. Upon completion, relaunch the game to assess the outcome.

  2. Upon reviewing your past campaigns, opt for the "Delete Campaign" selection.

Fix 4: Identify Unexpected Files

In instances of a data mismatch warning, the game launcher generates a file cataloging extraneous install and mods folder entries. Discover this file using the steps below:

  1. Input %LocalAppData%/Larian Studios/Launcher/Cache into your Explorer's address bar and press Enter.
  2. Identify a text file denoting the game's version number and referencing Steam or Galaxy. This file should conclude with _alteredFiles.txt.

Fix 5: Rename the Larian Studios Folder

A method suggested by BG3's support is to rename the Larian Studios folder, potentially circumventing the data mismatch error:

  1. In File Explorer, insert %LocalAppData%/Larian Studios into the address bar.
  2. Spot the Baldur’s Gate 3 subfolder and rename it, keeping any alternative name except "Baldur’s Gate 3."
  3. Launch the game to verify the error's status.

Fix 6: Erase Baldur’s Gate 3 Cache Files

Preventing launch errors involves tidying up data caches that accumulate during gameplay. Eliminate these files to enhance the launch process:

  1. Access File Explorer and direct it to %LocalAppData%/Larian Studios/Baldur’s Gate 3/LevelCache.
  2. Select all contents within this folder and press "delete" on your keyboard.
  3. Ensure your recycle bin is emptied as well.
  4. Launch Baldur’s Gate 3 to gauge if the data mismatch error persists.
