The game crashes while the trainer is open, activated or not.
There was an update today too for the game itself, but yeah that trainer was crashing even before the update. I can make a video of opening 20 trainers fine and that single one just crashes. Not sure why. But the update today added alot of content if you are making your own maps, so that's good.

Yeah it actually seems to crash after that like in the character menu. Maybe I'll try activating it after i'm loaded into a map.
EDIT: If I create a character, load a map go into the map then press f1, then do all the fun stuff with the trainer, it works that way fine. Seems to crash activating it before character creation or even during. I got it working great though once a map is loaded.
