Yeah, just how do you yield, my mother also plays and accidently attacked people she was trying to save during a gun fight. Cant yield to them... any fixes?

Only way to possibly yield is to lower your weapon, and you can't always yield. Enemies who will attack you plain out like Fiends can't be yielded too, but townsfolk you accidentally shot or something can sometimes.

Put away weapon... but in the end, restoring an old save might be the only option.
