Can't upgrade soul of the brine king.

e; Just ran it a fourth time, exactly the same parameters except this time my map was normal instead of rare and I changed my Pantheon selection away from brine king and into soul of lunaris.


I have now 3 times put a divine vessel into my map device along with an Iceberg map.

The upgrade requires that you kill Otesha, the Giantslayer.

My first two runs, I spawned Otesha and killed him only to find my divine vessel is missing from the map device.

My final run I procced Jeinei Yuushu and killed her and my divine vessel is, again, just gone from the map device.

Has anyone been able to upgrade this Pantheon? Am I missing something here?

Same issue here, tried it twice. Divine vessel gets consumed but does not return upgraded.
