Ghost Mode option doesn't seem to work, or I'm using it wrong. I always seem to get into combat even though I've got it turned on.
Ghost Mode:
Toggle on and it's as if you are dead. Enemies either are confused, cannot see you, react to sound, or will not do most attacks. You cannot SAVE while in GHOST mode. For STEALTH this is an easy way to get around, especially if crouched.
Maybe you got screen burn-in from leaving it on in the same place for too long.
Yeah it was weird. I restarted my PC and deleted the save and it's fine now.
