It seems this has been fixed after a refresh from what I'm told  (had collected mine earlier in the day.)

I have the same problem and it has not been fixed. It says I missed the holy bond, even if I logged in before game reset time, which is at 1am UK time. Last night reset was at midnight???

It now says I have 19 days to unlock all missed rewards, but even with plenty of keys, it would not let me. The unlock button does not light up, which is very annoying. Actually the entire situation is. Now I have 3 holy bonds sitting there, I cannot get (1 in each server). Thank you for that!

Thanks for reporting it. We're aware of this issue, and the game team is currently investigating the reasons. From what I know, you should be able to collect the final reward with the Key today. Have you tried that? 

Sorry to hear about it, DejaVu. Is the button "Claim" still greyed out? If not, what happens when you try to click it? 

The unlock with keys option seems to be working for me now that the schedule has ended in all time zones.  Is anybody still having problems with it now?

I still cannot claim the last reward. I just tried...

This issue will not be forgotten till the players get taken care of  please be Patient  :) 

Please let us know if you continue to not be able to claim
