Unable to complete quest and cannot proceed further due to bug

In ACT 4 - The search quest

Entered excavation site and beat the first herald boss, while beating him I died and cut scene played. I clicked resurrect on the checkpoint and visit the place.

There was nothing I don't worry about the loot. Now I cannot continue to the next quest. Makarou is missing and I cannot enter naganu. I am able to teleport everywhere but in excavation site even closing the game. when I visit excavation site the whole map is visible and I can able to enter the boss area nothing happen after. It says I need to enter excavation site again :(

I'm stuck in this quest.
