basically i have all my games in /mnt/games/SteamLibrary/steamapps/common/ and my custom protons in the default location /home/maplepy/.local/share/Steam/compatibilitytools.d/

How do i fix it ?

What Proton installation have you configured?

User has configured default Proton version (CompatToolMapping): Proton-stl suggests that the Proton version has been configured using Steam Tinker Launch. If so, you should try launching Winetricks using Steam Tinker Launch instead; it should be mostly the same thing feature-wise as Protontricks.

[maplepy]

Using winetricks through stl is very bad atm. It can't do much and it's very bugged

Also I haven't configured any Proton installation, just downloaded protontricks, tried to launch it and that's it

[Matoking]

You seem to have configured Proton-STL as the default for all Steam Play games (Steam -> Settings -> Steam Play -> "Run other titles with:") , which means you have to configure each game to use a non-STL Proton if you want to use Protontricks.

[maplepy]

Well STL will still use a proton of some kind though

For MO2 the situation is special, since it is independent from the wine version originally used for the game.

In STL you cannot change the proton version, it is hard-coded. Stable has Proton-16, Development has Proton-27.

If you want to use your own wine version you need to start mo2 from console and set WINE variable to point to your wine version.

I had one Proton-based wine that could not update the prefix, but for the prefix used by steam the prefix was updated with a different wine.

Since the prefix has only a few files in users/steamuser you can recreate the prefix from console with protontricks or winetricks by specifying your prefix folder with the WINEPREFIX variable. Afterwards copy back those files to the newly created prefix.

But all this is beyond what the script or STL offers. When I have a wine proton release that is not supported by steam but has patches that are needed to run the game at all, then I use this method (which should be rare).

For the latest mo2 2.5.1 I have found only one github repository that provides daily proton builds having the patch from wine 9 to run the latest mo2.
