I encountered this problem a couple days ago, on my 3rd run through, doing the list in order (top to bottom). I submitted a ticket, with screenshots yesterday, when it was still an issue after 2 days.I usually started my dailies by sitting on a sunken chest, until I killed 10 krait, and then opening that chest for the day with my daily key. When I arrived at the chest, the words weren't there and it showed as open. I killed my krait, collected my key, and tried the chest anyhow- no luck. All the others without checkmarks on my list show as open with no markings, and no ability to open them.The only things I may have done differently was trying to open the chest less than 24 hours after the previous one. My krait key daily had reset, though, so I didn't think there would be any issues. Side note, I was lucky enough to receive one extra key drop the very first day of the update (fractals drop) and another the same day the error began for me. (or the day after, not sure...I just know I have 1 more key than I should for the number of days I haven't been able to open the chests) I'm not sure it was that key, as it didn't cause problems for me the first day, and I already wasn't able to open them when I got another random extra as a drop.
