Ascent to power Normal bugged

Hi,

i did Balabala with my friend (we both lvl 20) and the barya dropped but i forgo to pick it. Later i remembered i needed to do the quest for ascension. I killed the boss 5 times. Nothing dropped. On my friend instane he killed it once and the barya droped and he was able to do quest to the end.

Can someone please help me ?

Thank you.
