Basically the quest starts and there is no dialogue or objective markers like there's supposed to be according to walkthroughs. The objective text states "Investigate Hive Activity: Head to Sorrow's Harbor and investigate the strange Hive congregations within," but nothing occurs if you head to Sorrow's harbor or kill enemies. It seems it's bugged in it's entirety.

This might be better suited as its own post, but I’ve encountered this issue on the quests Cold Boot and Risk/Reward as well. Anytime there’s a public event in the area, it takes precedence over the quest and doesn’t allow the quest steps to prompt. The only way around this seems to be pure luck; join an area zone where no public event is active.
