I'm running the Directors Cut Enhanced version of The Witcher game with the 1.5 trainer. I haven't tried all of the functions, but three that I have tried don't seem to do anything. Those are the Pause Monster function, the remove drunken effects function and the 255 items function. Two of the three are also the only two functions not on numerical keys, which may not mean anything. Pushing any of these keys gets no response at all. All of the other keys I've used result in an audio cue from the trainer and something changes in the game. It may not be immediately visible but something happens. Not with / or * or 0.
Am I doing something wrong?
