Thanks for the recap!
Yes i talked to the northwest and south guards and to Ethel Tinsley, checked all the area for the drones and already shut-down the panel and i don't see Inez anywhere.
I have a save just before the first encounter with her and another one just before finishing the quest with Milverstreet.
I first didn't know she was supposed to be there so if i finished the quest for Milverstreet and continued exploring for a few hours (probably did a quarter of the island).
I'm not sure Obsidian is even working on a patch for this since the issue is marked as fixed on live.
Now i'm wondering if, while waiting for a potential patch, i shoud continue with the last save i have or go back to before finishing the quest (which implies losing a few hours and re-exploring what i already did …)
