Trial of Chaos quest Ultimatum starts 10 rounds instead of 4 after simultaneous death with boss

I encountered what appears to be a bug with the Trial of Chaos Ascendancy quest.

I was completing the 4-round Trial of Chaos for my 3rd and 4th Ascendancy points using the quest item Chimeral Inscribed Ultimatum (Area Level 38, Number of Trials: 4).

During the final boss encounter, my character died at almost the same time as the boss. The boss was killed after my death, likely from damage over time. After that, I did not receive the Ascendancy points.

Current situation:

My character still only has 2 Ascendancy points.
I still possess a Chimeral Inscribed Ultimatum that states:
Area Level: 38
Number of Trials: 4
"Completing this Ascension Trial will grant additional Ascendancy Skill Points"
However, when I use this Ultimatum in the Temple of Chaos, the trial starts as Round 1/10 instead of Round 1/4.

Expected behaviour:

The quest Ultimatum should start a 4-round Trial of Chaos and award the 3rd and 4th Ascendancy points upon successful completion.

Actual behaviour:

The quest Ultimatum starts a 10-round Trial instead of a 4-round Trial.
My character still only has 2 Ascendancy points.

This occurred in the current league after the league launch.

I used ai for this, cause my english is fu*ked

I am encountering a similar bug. Number of trials is 4, but when I enter it’s 10. Once I reach the 3rd trial there is a group of monsters I’m supposed to kill, but the tower they are on won’t descend. So I cannot continue.
