Having the same issue with perks/abilities. Not sure if it's the trainer, or the game, or a mix of both conflicting with each other.
Also, does the dragonshout nagasaki work in fights for anybody? I learned it, and it says I can take out enemies with it, but I can't seem to use it in a fight since it doesn't show up. Not sure if that's trainer related like the perks/abilities or game related.
I also can't get the health to work, it seems neither of the health cheats want to work properly on my steam version no matter what I try.
Nagasaki doesn't work in fights no, unless it only works on low health or some other trigger.
You only use it for a maximum 7 times in the world. Could be more, since I still have to find 3 kids and 1 tramp camp.
