Do you have Easy Hunting on? It seems to make things unkillable.
Here is what I do to run the trainer, and I have had no issues yet:
Run trainer from trainer manager, run RDR2 from desktop, once RDR2 has loaded I enter story mode, once my save loads I alt-tab onto trainer window and press F!, then I activate 1,2,3,4,6,7,8,9,*,+,-,.,F1,F2 (I only use F3 and F4 if I'm entering a mission sometimes, I rarely use either as I just pay off bounties if needed). I only used the set money on pickup at the start by setting it to 10,000 looting an item then turning it straight back off again (all via alt-tabbing).
Hope this helps, I've had no trouble at all. sorry to those that have. Good luck!
Easy hunting works fine with killing animals. I’ve walked up next to many animals and killed them at point blank range. However if there are other animals around they will still run after their friend gets killed.
Also you still have to read the compendium to make sure you are hunting with the right weapon(s).
Only issue I’ve seen with easy hunting is it doesn’t seem to work on legendary animals. They still flee or attack you on site after finding all of their clues.
Thanks for the update, like I said, I didn't try using it as many thought it to be buggy.
I your using "no fall damage", then try without it. Seems that sometimes this is causing some unwanted side effects. Unkillable NPCs and animals.
It literally tells you this in the option's description. This is why Cali gets mad.
