Right, my game has bugged pretty badly.
I fast travelled to the regulator hq to turn in ome fingers. There was a radscoprion outside but I ignored it, running into the building.
What I found when I get inside was Sonora Cruz fleeing. I couldn't talk to her, and she ran out of the building and I haven't seen her again. And my last save game was 3 hours before...
I checked the wiki, and it seemed that the only solutions involved using the developer console, which I couldn't work out how to work. It told me to use the kill, resurrect, and bring to player commands on her (her reference number being 6f212), but all the permutations of how those commands could be entered didn;t seem to be working.
Anyone have any advice?
Thanks!
