I was running Tami Baker's arc earlier this evening, and while in her second-to-last mission, I ended up hitting level 16 (beyond her typical range). Any other contact, this happens, and because the arc is open, you keep getting missions. But Tami just cut me off, leaving all her the clues from the arc in place, but refusing to give further missions.
You can see the messed up tab here:
And the clues still active here:
But nonetheless, Tami won't talk to me:
I did do a petition about this, too. I suspect that when the character leaves Praetoria, this would settle itself, but I'd like to do this more organically, so I'm hoping maybe even the final mission (there's only one left, though it has both a door mission and then a delivery) can be forced back onto the character, too? But either way, I'm pretty sure she's not supposed to work this way, because no other contact does.
