I'm 20+ hours into the game, and i'm having a big problem. Vendors in most of the settlements won't barter with me. For example, I'll walk up to Arturo in diamond city and activate him, he'll say "feel free to test the grips" or one of his other generic lines and then nothing. No dialogue options or barter window come up. This happens at most of the other vendors in the game too. The only exceptions seem to be the ones I assign to stores at my settlements. It also started happening to many of the quest givers in the game too. Same thing happens, I activate them, they say a generic line of dialogue, and no options come up. I can't turn in any quests, or talk to someone to complete an objective for one. I'm stuck on "the Molecular Level" because I can't talk to Sturges, and for some reason console commands won't work to put the quest to the next stage. Short of completely reinstalling, is there anything I can do to fix this?
