Can't say I have seen that before, it does seem a bit similar to the old one that would reset the day one dialogue though. Let me ask you this, did you use the mouse roll back mod some people were talking about? Scrolling up seems like it can really break things in this game.Giving myself one bump for tech support (since some real knowledgeable people have posted over the past week). If this doesn't lead anywhere, I'll call it's a wash, take a break, and play from scratch at the next update.
Thanks!
My best advice would be to reload a save from before it happened, and if you are using that mod, don't roll back.
