Forget the name of the map now. The 3 bosses resemble 3 Harvest bosses, they emerge from plants one by one and then go into an invul phase as each is defeated in succession.

We entered this map through Zana, with the mod of Twin bosses. Only one set of bosses emerged once defeated the zana quest tracker said 3/6 bosses killed yet nothing further spawned. Making the map uncompleted under these conditions.
