Mismatched Data Bug?

[GrandMajora]

Okay, so ever since patch 9, I ran into a bug at the launcher saying that it has mismatched data which could be caused by mods or corrupted files. I have no mods with this game, I have never used any mods with this game, with the exception of accidentally joining multiplayer games that were using hacks.

As for the corrupted data, I have followed the steps laid out in the support section multiple times. I've deleted files and folders, I've verified the cache, I even uninstalled the game (just finished reinstalling it today), and I'm still encountering this issue.

After seeing that several other people were complaining about the same issue, I figured I'd uninstall the game and wait for them to patch it. That was quite a while ago, and I come back to find the issue still has not been resolved.

I have no idea what's causing the issue, I've run every possible fix the support section has suggested several times, and it's still saying that the data is corrupted or mismatched. At first I was irritated, but now I'm getting legitimately angry, because the game is coming out in just over a month, and if my game keeps crashing because of an unfixable error with the cloud data or whatever, I can't get a refund at this point!

When you uninstall your game, not everything gets deleted neccessarily.
Uninstall the game, and manually delete the left over files.
Also make sure there are no files in %Localappdata%\Larian Studios\Baldur's Gate 3\Mods
Uninstalling the game doesn't clean this folder either.

Edit: To be more specific it can happen that there are left over files in
\Baldurs Gate 3\Data\Generated\
and/or
\Baldurs Gate 3\Data\Public\
And if you don't delete them manually, they will persist through a reinstall.

So should I delete the files, or the entire folder and just reinstall everything from scratch?

Uninstall, manually delete everything left over, including the folders (But the folders aren't that important, just to be save to not have overlooked anything) and then reinstalling should fix it.

Alright, I couldn't find the Data Generated or Data Public files, so instead I deleted every folder named after Baldur's Gate 3 I could find. Both the one in my Programs Files, and the one found in the Larian Studios folder with the launcher.

Cleaned out my recycle bin too, just in case. So now I'm doing another full reinstall... after I just got done with the previous 7 hour one...

I had the same problem and had to delete this folder too > C:\Users\your user name \AppData\Local\Larian Studios, as it also persists through uninstall too.

You can also check in folders C:\Users\your user name\AppData\LocalLow and C:\Users\your user name \AppData\Roaming , for any Larian folders

C:\Users\your user name \AppData\Local -> can easier be reached if you use %localappdata%
and for the mentioned error only the things in the mods subfolder should matter. If you delete the whole %Localappdata%\Larian Studios\Baldur's Gate 3 folder, you will also loose any potential savegames and your settings. That's why I didn't tell to delete the whole folder.

Settings is the most probable cause of the data mismatch. Was for me also.

Okay, that's new to me, when I looked it up a couple of month ago it was about left over files from modding. If that's so, then I'm sorry. Sp in that case you might also wanna delete the
%Localappdata%\Larian Studios\Baldur's Gate 3\PlayerProfiles
directory, if the above didn't help

Most reasonable action is always delete all in these cases. Only keep speciffic saves if wanted. Otherwise there is no point of trying to figure what is the actual conflict as settings and everything else is so easy to setup again.

As I said before, I've already followed the steps listed in the help section of deleting those mod files and stuff (I don't even use mods) repeatedly and that didn't work. So I decided to completely delete the BG3 folder itself.

I did not delete the Larian Launcher folder, because I'm not sure how that would have effected my other Larian games such as DoS 2.

I don't care about losing save games, since that was already happening every time they released a major patch to the game.

I do not know where support pages point but in my experience Larian has had BG3 files in three locations + game install folder. One conflict was born when they moved some files to other place

Folders
C:\Users\<UserName>\AppData\Local\Larian Studios\Baldur's Gate 3
C:\Users\<UserName>\Documents\Larian Studios\Baldur's Gate 3
C:\Users\<UserName>\OneDrive\Documents\Larian Studios\Baldur's Gate 3 (Your OneDrive location can vary. This does not exist of course if onerive is not in use)
Game install folder.

Deleting these all if they exist usually solves conflicts.

♥♥♥♥♥♥♥♥♥♥♥♥♥♥, even after completely deleting the BG3 folders and reinstalling the game again, I'm still getting the error on the launcher.

I don't have the patience or energy to do a complete reinstall a third time now, as this game takes 7-8 hours to fully install.

Maybe if I delete the Larian Studios folders completely? I think the only games I have on it are BG3 and DoS 2.

You do not need to delete game folder again if you already did it once. Deleting the Larian folders on all possible locations will most likely be enough like you thought.

If you have not deleted game install folder ever (just uninstalled) then it might be required.

[GrandMajora]

Oh, something which I also noticed is weird, is that I have two folders with the following names

Larian Studios (two words)

LarianStudios (one word)

Both have the Launcher folder and appear to have the same files.

The support page points to

%LocalAppData%\Larian Studios\Launcher\Cache

and says to look for a file named "altered files".

When I opened it, it said that the altered / added files it detected were:

bin\BG3.exe

data\localization\english_animations.pak

data\localization\voice.pak

I just deleted these and am now verifying the integrity of the game caches as I write this. If this doesn't solve the problem, then I'm completely out of ideas.
