Jungle Valley Boss not in Ritual Encounter

I have been running maps all day to try to capture them for the "Ritual Encounters V" challenge. I have had the same bug happen twice now where upon killing the Queen of the Great Tangle in the Jungle Valley map, the boss does not then appear in the following ritual encounter.

I am 100% certain that the boss died within the ritual circle, as the ritual takes up almost the entirety of the boss arena. I bottled both rituals anyways after to check that I did not kill the boss in the ritual encounter without noticing, and no unique monster is listed on the Blood-Filled Vessels. I have not had this issue on any other boss, and have bottled a significant number on this character using the exact same gear and skills.

Alright so I've been running Valleys all day.

2 things can happen when you get the ritual in the boss room:

1 - you can start the ritual BEFORE the boss actually spawns (cause it has the add phase)
2 - the ritual cannot be started unless you actually kill the boss.

In each of these cases i did not capture it, and i used around 12 vessels so far.

So definitely a bug.

Definitely a bug here.

Been doing Jungle Valley 5 times with the boss in the room as ritual.

Boss was killed before ritual started. Boss was killed within the circle as seen in screenshot. After that, boss did NOT appear in the ritual, and could NOT be captured in the ritual vessel.

Could you please fix this or change the league achievement to not need this for completion?
