The last trainer was made in 2018. Since then the game version has changed and it isn't very compatible with the trainers anymore. However, I managed to get 2018 version work so I'm playing a bit older version of the game which I don't mind since in 4.1.6 the devs removed a lot of fun stuff, code broke thus some quests are buggy, damage indicators are missing, often the dealt and recieved damage is incorrect etc. 4.0.3 is my choice.
