Some super mutants attacked my settlement, and ever since then, none of my settlers do what they're supposed to do. The shop keepers just say "thanks for your help with the super mutants" and all I can do is say things like "glad to help". There's no barter option. There's no trade option. If I try talking to them again, the same thing happens perpetually. I tried fast traveling back and forth, same problem. I tried waiting 24 hours, same problem. I tried restarting the console, same problem. What's the deal? Why won't they say anything other than "thanks for the help!" etc.???
