after completing a community event.. it's normal the player checks in less times per day.. but I'm sure the major part collect to help gain community points anyway, which are at max drops, so add alot of points.
we have all suspected what meme and huckletown said, but it costs us only a split-second and 1 energy, so little difference to the player not to do.. but.. great hopes to those players who were not able to finish the event and hoping at least for the final community prize. it would be sad if this players, even if it would be for the first time, miss the prize.
