well sounds like something I have done before
ONLY not knocking, but if it was me, after climbing down in the AM to get the quiver, I wouldn't have gone back to that stand, as it would have been very easy for them deer to bust you and ruined a sweet set up for later on
I would have sat on the porch and seen for sure where they came out at and what they did, rather than push my luck, that already went down hill
SO again, not bashing, just saying, going in later then you wanted having to wait till light to find a tree then going in again with your quiver, that puts a ton of scent and disturbance in that area, and possibly you could have been seen thus busted for sure, and why they didn't show up, they very easily could have seen you and went a different way
and now thrown these bucks off there patteren they had for so long
I hope I am wrong for you, but that would be my take on th events you wrote here
But best of luck next time
