After they go to Sanctuary the next quest is to go meet the settlers on the bluff and have you go to Lake whatever, get into the gift shop and take the raiders down then go back and inform the settlers. I haven't even gotten the Corvega quest yet. Now I'm reading that part that I played last night isn't even there? I have no idea, did I have another quest? I didn't clear out the Corvega plant totally just the outside so informing the settler wouldn't make sense with that. I'll have to check when I get home because I'm lost. The settler said "these guys are bothering us" and a quest marker said to go to the gift shop, went back and said I did it and I was done...but it was supposed to be the Corvega plant?
