re: 'Crash your game, note the time, wait for a significant amount of time (longer than what a eventual timeout etc would be; maybe an hour), then open the game, check presents and look whether they were given to you in that moment or way earlier'

=> A day or two ago, I was dc'ed just after a Round Battle, (not by design), and thought I had lost any chance to choose or recieve panel rewards .. but they appeared in the Presents, anyhow .. so this seems plausible.
