Cemu 2.5 doesn't install title updates

[Vins98]

Current Behavior

Cemu does absolutely nothing (not even giving an error message) while loading an update (both via the "Install game title, update, DLC..." and the title manager, selecting the meta.xml).
Manually installing the update (moving update files to their proper location in MLC/user folder) still shows nothing on the title manager.
The game I'm trying to update is Tekken Tag Tournament 2 (European verison) - TID: 000500001010f800

Expected Behavior

Cemu correctly installs the update.

Steps to Reproduce

1. Have your decrypted game in a user-defined folder
2. Install an update
3. The game version remains untouched, as does the MLC folder

System Info (Optional)

OS: Win 11 24H2
GPU: RX 6900XT

Emulation Settings (Optional)

Stock (tried to delete Cemu folder and extract the emulator's zip again).
I Also tried with Cemu 2.4, and I got it working using a really old Cemu version... 1.27.1, using the exact same files.

Logs (Optional)

No response

this means your update dump is missing necessary data.

this means your update dump is missing necessary data.

This would be the case if not only it didn't work on earlier versions of Cemu itself, but also on a retail console. I installed the update on my WiiU without any kind of problem.

The update has both the code folder (containing a perfectly working rpx alongside its metadata) and the meta folder, containing each needed file.

Also, if that would be the case, I guess it would be better to make the error management more verbose, returning an error explaining the issue to the user instead of returning absolutely nothing.
I'll do more investigation on more titles, I have a Twilight Princess HD DVD that I could dump using my WiiU, I don't know if there are any updates for the title, but I could try replicating the issue on that game as well.
Merry christmas btw, and thanks for your reply 😃
