This is really odd.
I have completed all the activities each week of this event. I did one bonus quest, as it was the only one that I had a pack for, and I don't believe that even if you skipped that one that it would have an effect on points (as I had to do that the rest of the time). It's evident that I have done it all, but somehow for completion's sake, I didn't accumulate all the points, and lost out by a narrow margin of...10 EP? What is going on?
There are no activities this week (until the end) that would allow me to catch up. It's clear I could get everything, but I missed one because of a small amount of points somehow wasn't applied? There is no way I missed an activity AFAIK once the quest list is exhausted.
