The cutscene is still failing to play after the Last City Override as of today in Season 15. My partner is working on the Splicer title but will be unable to finish it without the triumph. We've played through it three times, the first two were together and the third was solo. They've tried logging out and logging back in to no avail. They have only done the questline on one character, and it would be beyond unreasonable to expect them to play through the entire seasonal quest over a bug like this - is there any incoming fix for this?
