I have and had the same issue at least three times within the last year. As far as I remember it was twice within the last weeks. I get green hooks for all days lets say of the last three weeks which IMHO is possible only, if I had the streak. Though, I was bombed back to stone age again and again (from 5x to 1x bonus) which isn't funny if there was a 1K Infiniar bonus pronounced for this or next days.

I assume, that there might be an issue regarding bad or changed network connection. After that or in case you are online again the state "solved" of a daily quest might be transmitted. The timestamp used might be according to the transmission instead of to the quest to be marked as solved. Obviously there are different timestamps used: one request for the green hooks, <timestamps[days of all solved daily quests]> and one request for the streak consisting of consecutive <timestamps[points in time of transmissions for a quest marked as solved]> containing the max(timestamp).
