Same issue here, tried with neutral rep and Int 8, Cha 6, Lvl 41. Also the Chef in Hub (In the Postmens building) doesn't talk to me, so that i can't give him his desired ingredients. This issue exists with other Npcs when you don't have the neccessary stats, but in these two cases it seems bugged. I also have this issue, at least with durango, with all my other chars.
