So I just went ahead and fought kondreiu for the first time but when when me and 2 other players went into the boss room only one player got the cutscene and the other 2 players did not see anything except our party member getting killed. We tried to walk up to the rock to trigger the cutscene but nothing worked. After our pt member died for the 3rd time they decided to return to pioneer 2 and then the cutscene played for us while our 3rd member was trying to come back to the boss.
