I first encountered this quest while running through the area away from an angry mob at night. The assailants focused on me instead of Ralph and joined the mob for a little while.
When I returned later to investigate the mission, Ralph only had one assailant and after killing him, Ralph seems to still be doubled over and acting as if he's still being punched or kicked, but no one else is there.
I don't have the option to talk to him at all, I've sucked up the motilene around him (which took a few tries as the machine kept acting as of the action was completed, but wasn't. But I managed to keep doing it and persevered in the end)
I'm playing on the Xbox series, any ideas? Game reloading unfortunately didnt help.
