Ive been playing the quest line the silver shroud and I'm at the part where its says "Meet with Hancock as the Silver Shroud" But the issue is when I click on him to talk he wont talk because he keeps telling me to go kill bobbi from the big dig quest and is stuck in that dialogue loop. I could go back a save and fix this but I would have to go back really far and I wouldn't like to do that if anyone knows a way to fix this or get around this please tell me

maybe finish the quest with bobbi before you continue with this one?

Ive already finished that quest and I tried to go back to see if she was there but she is gone now
