the problem they had is that i don't believe they had testers testing it by that fact i believe their is so many errors and bugs going on.
NOTE P.S.
If you want to use the trainer with the game after an update do the following.
right click the game in game menu on steam
properties
and in the drop down menu for updates say do not update this game automatically. and walla you now can use the trainer im still on 1.15 for my game i will deal with the bugs till the trainer is on 1.17 or 1.18 and theirs a trainer for that.
you have to run it in offline mode too or else it will patch when you load the game, don't forget that
