No the system updated the launcher and the fonts just vanished. Without knowing what exactly caused the font package to be removed, I assume it was the update to the launcher. As stated above, this didn’t make the client unplayable. All I did to restore the core fonts was the winetricks terminal command posted above.
Yesterday, I noticed another minor visual issue with the alpha textures within the client. I am currently looking into this visual issue, where the explosions transparent parts appear as opaque black instead. This will probably be an issue with the recent graphics changes made to the game and probably need to be addressed in a separate thread.
I am currently running Manjaro OS ( Arch Linux ), no Steam, no Lutris, straight Wine version 10.4. But thanks all the same, don’t want to muddy the water with additional launchers.
