Earlier today I queued a green chest and 2 blue and when I returned, the 2nd blue chest was being decrypted but the green and first blue were missing. I tried resetting the game and checking if maybe I had a cloud save I could restore, but nothing worked. This 2nd time I've had this issue, and only one of what seems like several timer bugs with chests. However, any problems I have had have been reported already (i.e. timers resetting), so I see no reason to go into detail here.
