Playing on Xbox One X via Game Pass.  When talking to Pavarti to get the quest "Don't Bite the Sun", the quest fails mid conversation as soon as you accept it.  When checking the botched missions, it gives the reason for failure being that Pavarti has died.  This is on normal difficulty.  She's also still usable as a companion, but you can't get any further with her companion quests because the game has her flagged as dead. 

Hey, Zatarain

I'm sorry for the quest issue you have run into. We have our development team looking into it and hope to have a fix for it shortly. In the meantime, to expedite your request, you can send an e-mail to our publisher, Private Division at support@privatedivision.com. This will get your issue into their queue and allow us to prioritize requests to ensure the fastest possible turn around time.

We apologize again and thank you for your patience while we work to resolve the issue.

I have just had an email from Private Division support about this issue, reply may be of use:

"I'm sorry to hear that you've encountered a bug where your companion has been marked as dead in the quest log, despite them still being alive.

From what we've discovered, this bug can happen when your companion is climbing a ladder while you start a conversation with an NPC. This causes the companion to continue climbing the ladder forever, and then meet an untimely death when the conversation with the NPC ends. Make sure that your companions are not climbing any ladders before you enter a conversation and this should hopefully prevent this bug from happening to you again until this bug has been resolved.  Please note that we currently do not have an ETA as to when this issue will be fixed, but we are actively looking into it.

Sorry for the trouble, and please let me know if you run into any other issues."
