Kriar village /interlude bug

finish the whole page 3
but the boss didnt even marked as done didnt get the reward
tried 4 times already and i already did the let him follow the 3 wisp and killed him
and i didnt get any of those award i cant get my 40 spirit buff
the map got bug i finish the whole act there on interlude

I'm back after a long hiatus and continuing my journey. I haven't received any rewards for the interlude chapter with the Yeti, Kirar...
So I'm also wondering if there are any glitches in Act 4.

I see that the bug has been reported by quite a few players.

Have you found a solution to restore the bug?
