I'm sorry for the mistake.
Medea, you are some kind of veteran. It's good to see you here too.

I've tried to ask some help directly on the Steam Workshop page of the mod, but it isn't updated since 2022, so I don't have much hope..
Maybe there's something wrong with those files : winsys.xdb and micsys.xdb ?

Maybe, this could help.

Hello everyone,

I have a problem with the latest version of TQVaultAE (4.4.0). The Vault works perfectly with "vanilla" characters, but seems unable to detect Caravan-related files for characters associated with a mod. I searched for information, but was surprised not to find much evidence. A conversation on Etienne Lamoureux's GitHub suggests moving the mod folder (called "mymod") from where it is stored (it's a Steam Workshop mod), namely in SteamApps/Workshop (..) to a "CustomMaps" folder (which must be created in My Games/Titan Quest - Immortal Throne (..) ).
I obviously checked the custom games detection box in the Vault configuration tab.
But that doesn't fix anything. I try to launch the game and contact the caravaner, but the creation of the files associated with the 3 different chests in the caravan are still not detected by TqVaultAE.
Does anyone have any idea of ​​a solution or has already had to deal with this problem?
Thanks in advance
