Zolin and Zelina bugged

Had the same problem, just made new instance of the map and it worked.

Last run, my character died after one of the bosses died and I couldn't get the scenario to start again so I had to reclear the map. Thought it was due to dying and leaving one alive. This character, I died while both were still alive and now it's bugged and it looks like I'll have to reclear the map AGAIN. :(

Edit: Reset the map, now the small cores won't let me into the 2 treasure rooms. I have both cores in my inventory and neither room will let me in. This feels absurd.

Did I win? Seems there's nothing left to do...

Oh, wait. Recruit the Vaal isn't the final quest?

Same problem, I had to reset the instance each time I died to try again. Really annoying.
