Can't progress the quest "Tango with a Tracker" because of game crash.

This is what I hope and that it will resolve itself. Until it resets, however, there's nothing comes to mind to fix it from my end.

There is no issue. You failed the BC, thus you need a new KI and you can get one on the next conquest reset. What you see is not a bug.

This fight, the associated quest, and literally every single mission people come here to post about it being bugged, 99.9% of the time it isn't, and they just overlooked something or didn't read everything.

Quests like this have been in the game for 15-20 years. if it was bugged it would have been found by now.

and with GM's suggestion as posted in the original post, I still believe that this is a bug.

GMs have no technical knowledge about the game- they aren't Tech Support, they're player support. Anytime you say you think something is a bug they tell you to post here. It doesn't mean there actaully is one.

GMs resolve desputes, enforce the rules, execute the one time item restore, and unstuck you if you're stuck in the world geometry. That's it. You can believe what you like, but there is no bug.

If you fail that BC for any reaosn, whether you crash, or leave, or disconnect, the miasma target will say what it says in your screenshot and that NPC will say what they say, until the time comes you can get a new KI. This is 100% normal behavior and not a bug. if you're alone any crash/dc will result in battlefield failiure immediately.
