What happened to Zana's voice this league???

Is it lore related???

She sounds as if she's permanently high or something...just terrible..

The volume level is off too. Not only was it re-recorded (it's not clear to me if it's the same voice actor or not), but the volume is much lower than that of any other voice.

If I wanted to hear her voice properly, all of the other voices would need to be much too loud.

As it is, I've been able to make out what she says, but only by listening for it a couple of times.

They surely added a lot of Zana voices. Also, most characters now have goodbye and greetings quip - either they used not-yet-implemented audios in content or have done them anew.
As for Zana, I've noticed immediately she has become... softer. A lot softer in voice. Even when she scolds you like a very dumb Exile for playing with mechanic plaything given to you by a stranger eldritch woman floating she had a strange motherly feeling. Must be my imagination.

Or perhaps, she actually partied hard with Niko and Vinderi. I mean, the whole Maven thing can be summarized in a "Lucy in the Sky with Diamonds", so...

Yeah, I don't know what happened. And so far, nobody has given us a clear answer, ie if it's lore related and had to do with the Maven or it's something entirely different...

It's definitely weird though..
