No, dialog with Maria should not automatically set everyone to hostile, unless you threaten her or tell her of your plan to steal a vertibird. Two questions: Do you have any other mods (or another version of the vertibird mod) installed? Also, what were the other things you did at Navarro prior to this happening? (Maybe there is something there setting the wrong global variable.) As for the karma/Vault 14 issue, I think I got that resolved a while ago, once I discovered the wrong script attached to the entrance map. I'll know for certain once I get there in this playtest.
