Admittedly, my first reply, to freqlectic, was rather unfair, since my perception of obviousness is probably not the same as someone else’s, so I apologise for that one.
The thing is I did check everywhere in the quests and I cannot find anything. The completed quests where the rewards are redeemed are not visible, and, yes, it is highly likely that I finished them and claimed them, but, and that is the question, how do I know that? I.e. which frame should I have, which picture should I have? Should I have something else? Since the event was extended, should the countdown be present, because it’s all zeroes for me?
