Disease Vector (Catalyst) on Outbreak Perfected "Requires Purchase"

Hello, after completing the Zero Hour on Expert difficulty I did not "receive" the catalyst (didn´t get unlocked). I thought it was strange and that I may have made a mistake so I completed the mission again as suggested on the following post, with no luck: [url]https://www.bungie.net/en/Forums/Post/263958826?sort=0&page=0[/url] I am 100% sure that I completed the right mission in the correct amount of time more than once (see linked screenshots as proof) so it can´t be a "visual issue" as mentioned in the post linked above. How can I unlock the catalyst after spending multiple hours trying to get it?

  • Hello there, Thank you very much for the detailed report and for reaching out to us. I'm sorry to hear that you are having issues with this particular Catalyst. If you haven't already, please make sure to visit ADA-1 and ensure that you've completed the Outbreak Refined I, II, and III quests on Expert within the time frame allotted. If you have not completed these quests and cannot find them with ADA-1 (or in your inventory), please check the Quest Terminal in The Tower. You should need to locate some switches in the mission to get the Catalyst.
