Find Missing Key Bug

Yeah I have this problem as well on the ps4. I didn't even notice it was an issue until much later it has been driving me mad just sitting there taking up space. I have tried everything to get rid of it but to no avail. 

I have the same problem. Tried loading a save before the winter palace quest and it is still there after finishing the quest for the 2nd time...

same problem here, i play on XBOX ONE and its 2 days later now and reloaded and restarted my xbox 4 times and it still shows that stupid quest i really wanna get rid of it 

Same here, on PC. More than 10 hours of gameplay since the bug occured, around 3-4 days ago.

same on 360

Same here (PS4). I see this was reported several weeks ago, but it wasn't fixed in the last patch. Can we expect a fix anytime soon?

Same here. Tried going back to earlier point in the Winter Palace and even chose different outcome, but the bug is still there. On PS4.

This is a total *, where is support, why do we need to wait and spam like idiots for someone to fix a problem. This is very annoying. EA fix the * ! 

I will spam every day, until someone fix the lame bug. Where is the point in having a technical forum, where no devs are involved ??

Same here.  I was purposefully keeping missions selected as infrequently as possible so when this happened it sucked a lot of fun out of the game I don't know why.  I've put up with a lot of other bugs in this game with a lot of grace but this is unforgivable.  That mission "Wicked Eyes and Wicked Hearts" was already a chore, why does it then get to ruin the rest of my playthrough with this annoying message?
