the latest trainer we posted was posted to help with that issue.
Its a game mechanic. Your health you have two meters, the heart and then the actual health meter. The health meter is when you take damage, the heart meter is when you are tired or take damage beyond the health meter. Same for Stamina and Dead Eye. This is why you have to eat or drink or do tonics, etc.
No idea if Unlimited Max Core Health prevents death, but the code that refills it isn't called but like once a second or two so I wouldn't depend on it.
The unlimited health option has been addressed further in the latest trainer we posted. Please use the top trainer and report if any more issues. Killing most anything can be done with headshots with either trainer, but the top trainer you can shoot people normally.
I can post a video of me taking out an entire gang with the trainer if you like.
Thanks for the tip on Unlimited Items. Money IS an item in the game, although the code location I picked to give you money seemed to be isolated for just money when you pick it up.
Regarding fist fights or unlimited health, try the latest trainer and report.
It literally works without fail here in multiple saves and conditions. I cannot make it fail..
Also, "doesnt" work is not a very helpful feedback.
