CAN"T PROGRESS CAMPAIGNE! - Final boss(brothers)

Hi!
I did the map with the whisp, killed the boss at the end and i got 40 spirit for that but still i have the question mark ? like whisp is not done
I killed the 2 brothers at the end , the hooded one showed and then i webt to town and nothing happened
Saw that i didnt killed YETI , went back and killed him, killed the 2 brothers again but nothing
On the mai, i still have the question mark at the map where you get 40 spirit at the end at final boss
Can anyone help with a suggestion ?

Thought about a visual bug? Or you don't actually get the reward?

You don't need to do any side content to finish the Interludes Act. You just need to kill those final boss on each interludes, then go back to the town in Act IV once it's done. You will then be able to teleport into the Endgame.

So if you killed all the boss, you just need to go to Act IV town.

Yep. ty
i was thinking i have to do something in interlude
