During this quest from Homestead, there appears to be a bug with the progression.
I beat both the miniboss dermapterans for their hearts and opened the door, AND then handed the initial ‘eggs in the field’ quest in for exp, but when I returned to Douglas after beating the Queen there is no option for me to hand the quest in to Douglas.
I believe I may have broken the chain of progression which has happened to me before. Usually I just do all the objectives at once and then hand everything in, and Douglas will accept that the Queen has been killed. The way I did it appears to have broken the quest flagging such that I have to kill the mini bosses for their hearts again to proceed the quest.
