So I've been playing F2 for a few weeks having a blast. Today, at some point in my play session, something has occurred which is preventing any NPC/monster from attacking me. For example, after fixing the air purifier in Broken Hills, I wanted to mop up the remaining ants and scorpions, but they won't attack. I can attack them, and then they'll fight, but they won't attack me. I brushed it off and went to New Reno - same thing - no one will attack me, no matter what dialogue options I choose, etc. The dialogue just terminates and then nothing happens.
Anyone have any ideas? I'm concerned because this may "break" parts of the game, or at least make it artificially easy, since I can go places I"m not supposed to be able to without being shot up. I'm running the recommended mods except restoration project. I've googled but haven't found anything useful.
