I don't know the reason, but after the update, the game only shows 34 mods and does not display the Valkyrie. However, the Valkyrie mod is visible in the game launcher and in the GP backend, but when I enter the game, one Valkyrie mod is missing. It is possible that the mod got hidden by the GP platform. Once in the game, all the Valkyrie mod items are gone, indicating that the mod has not been activated.
