@MrAntiFun I can confirm that the V0.1.5 Trainer does not work for Game Version 0.2.3 as of 12/17/2018. The Trainer does not register the game as running and thus none of the cheats can be activated. If you could take a look into the game and trainer at your earliest convenience, please. Thanks for all the trainers.
I am from Germany and unfortunately I have to use the Google translator. Also I can confirm that the former Trainer for Mist Survival does not work anymore. This is probably synonymous with the fact that the process name has changed. MistSurv-Win64-Shipping.exe has now become Mist21-Win64-Shipping.exe with update 0.2.3. I would be very happy about a new Trainer.
