It appears the gold cheat does not work with the steam version. Infinite health and infinite power works though, so I know the trainer is working to some extent. But both change gold, and the edit gold feature are not affecting the game. Tried collecting gold before enabling code too but no go.
Don't see any patches since March 1st, did you try the cleaner?
Please delete the trainer, custom keys, debug folder where the trainer resides and all files in
C:\Users\USERNAMEHERE\AppData\Local\Temp
C:\Users\USERNAMEHERE\Cheathappens\Work
C:\Users\USERNAMEHERE\AppData\Roaming\Cheat Happens\0x90
C:\ProgramData\CheatHappens
Learn how to make your own Trainer Cleaner for the above paths here.
Reboot PC to clear excess memory, get a fresh copy of latest trainer and extract it. Run trainer as admin, read the instructions and try again. At times, a new game may be needed to resolve failed options if the data in your save file was altered. Use on a new game and test the option. If it now works, quit to main menu and load your save and try it again. May also need to run the game without the trainer first and play a bit so the save file gets updated to use possible new values. This typically will resolve the issue.
This cleaner is also part of the new Cheat Happens Trainer Manager 2.0, it is found in the settings and has an easy to use one button click feature.
I've tried the suggested ideas. Uninstalled the game, deleted trainer, started a new game, unfortunately none of it works for the gold cheat. All the other cheat options work, including infinite hp, teleport, or even move left/right. Gold seems to be the only one that's broken. Oddly, under the editor, the gold will always reflect some other number other than the current amount of gold I have on me.
Best to report it for update then.
