Nope. Tried on three different devices and still couldn't collect.

Since the end of the last event I have "Teach me hard 1" stuck at the claim reward phase. I did not claim it before the event ran out and clicking claim reward now does only have the mission disappear from the list just to be back again when opening up the list again. Therefore I got a mission stuck in the list and did not get any present for fulfilling all the missions in the last two days.
