IIRC giving Mia the red outfit and her being fucked by the werewolf was unavoidable at first and a lot of players objected, so a reset was added and later replaced with a choice avoiding the werewolf entirely.think due she is so early on that she is like needed for lots of things later on. think the start isnt easy fixed to be more open ended like it is now.
I think Shakala is like that in the other direction...enough people complained that killing her permanently locked out all goblin content, so a respawn was added. I hadn't found PQ yet when that would have gone down so I might be wrong...
