Events Not Resetting & Magic Find Bugged
Oh forgot to mention, that my daily achievements did not reset again last night. The achievements reset but I did not receive a Laurel after completing the tasks.
This now brings my lost Laurel count to FIVE Laurels!!! I seriously doubt that these missing Laure’ls will be awarded back or refunded, but it’s a joke that I’m missing so many from bugs.

This will address your Dailies, chests, etc.
Magic Find does not apply to ‘chests/crates/sacks’, so that would not be applicable.
As to your other concerns, some adjustments were made to Dungeons per the patch notes, but whether it would impact your issues, I can’t say.
Good luck.
Just logged in to chime in here that the chests in dungeons have been nerfed, A friend and me run most dungeons every day and have found that we are getting much less greens than we used to and almost no rares (ran CoF1+2, CoE1+2+3 without a single rare, MF 192%) when before I’d usually average 1 rare per path.
