I've completed the investigation 7 times tonight. 4x on legendary, 1x joining a host, 1x on regular, 1x on legendary (PC). I successfully finish, meet with Finch, the countdown starts and then I get returned to orbit without being able to progress. TF IS GOING ON WITH THIS CRAP???!!! I've killed every add, including the 2 additional knights, before killing the wizard and ghost. the counter reads 3 of 3 each time..... I'm so fed up with this mess. Why is this happening almost a FREAKING YEAR INTO THIS MESS!!!!!!!

I've solved it. There are 2 barrier small knights that spawn with her. Both of these knights MUST die before you kill the wizard and crush the ghost. If you kill the wizard before these knights, they disappear and pick the quest. Good luck!

same here.... Can't play the game... I'm starting to regret giving them more money.

I have similar issue, PC/Steam: I completed the mission on my hunter on both Classic and Legendary, no issues; then on my titan, only the wizard spawned at end, killed it and finishered its ghost, and said "Defeat the Lucent Hive / Combatants Defeated 0 of 3"; backed out and relaunched at the same checkpoint, wizard and the two yellowbar knights spawned in together, killed all 3, only 1 ghost spawned, finishered it, "Defeat Lucent Hive / Combatants Defeated 1 of 3." Seems like the mission is bugged for some reason. Hopefully they fix it or the community finds a fix for it. Edit: Fix is to wound the Hive Wizard, which spawns in the two Hive Knights, and make sure one is killed and registered as dead in the Lucent Hive Defeated counter before killing the next Lucent Hive, and kill the Hive Wizard last (only way it worked for me on my titan). Hopefully this helps.

I am able to kill the ghost at the end and even get loot but the mission will not so Completed, as a result I am unable to continue the quest line. Having the same issue with a mission on the previous expansion. One thing for bugs, another not being able to complete the content that’s purchased 🤦🏻‍♂️😤😂 Hopefully patch ASAP.

I'm playing on PS5 and ran into this issue. I jumped off a ledge to die and respawned back in the same area. I killed the two Knights before going for the Wizard and this fixed my bug. The Knights counted as two combatants and then when I killed the wizard I was able to crush their ghost and progress in the mission.

Same here, I did the mission solo and didn't have any issues on PS5. But now running it to help a friend and hit the bug. So killed the witch, crushed the Ghost but it didn't give the completion

As it turns out this was just an ID10T error. I'm an idiot and figured it out the following morning. To perform the finisher on the hive ghost I needed to press the "G" key to finish it, not "E" key to interact. Hope this helps someone else, but yep. Sorry All.

I have the same issue as you, playing on PC, the issue is present for both gamepad and K/M. There is not even a "tooltip" which would display the button for the finisher. I wonder if the issue is not related to the changes mentioned below? Are you running any finisher mods? (I was but I also had full super and still got the issue) FINISHER MOD REWORK Finishers can now always be performed even when using mods that require Super energy. If the required Super energy is not available, the benefit will not trigger. Dev Note: With the introduction of Lucent Hive Ghosts and finishers being mechanically necessary to defeat them, the finisher mods have all been updated to behave differently. Now, regardless of which mods you have equipped or how much Super energy you have, you will always be able to perform finishers. If you don’t have the requisite energy, or you don’t need what the mod would grant, the benefit will not trigger, and you will not have Super energy deducted. For example, if you have the One-Two finisher equipped and you have a full melee and/or less than one-sixth of your Super energy, you will be able to perform the finisher, but you will neither gain melee energy nor be charged Super energy.
