I'm at the part were I need to kill the boesses. I told Cachino I'm ready to kill them, but all he does is stand there, and no longer reacts to my attempt to talk. Further more, the quest marker keeps telling me to go to him.

I'm royally [censored] right now, what do I do?

Reload a previous save?

I have learned to save often (and not just quick save) in this game
