@bielik01 Yep - the clue is already documented, but no solution to unlock it.

And I don't know about the clue respawn. Because this is the first time I have this problem, until now, I didn't need to verify if their respawn or not.

Actually I'm worried about not be able to complete the killing Order quest.

When I go to collect the note on the table in the church in Glowecestre, it disappears but nothing else happens. There’s no new info in the Order menu or anything in inventory. I don't know if we are able to kill low-rank members without having all the clue and it could be a problem.
Do you really need a video as a proof of the bug, or screenshots are okay?

Hello, I have the same problem, Oxenefordscire treasure hoard is always in my inventory after I found the treasure. I'm at 1.2.0.1 on PC. Do you always need a video as a proof?

Normally : "A" button for climb, "B" button for fall.

But regularly, "A" become normal attack and "B" use the bow. But when I go to the control options, nothing has changed. So, each time, I must quit the game to the menu and reload the save to solve this problem and having normal control. It's very anoying because this bug happen regularly randomly, but quite often.
