The new attendance event lasts 14 days and is only available from Oct 18 - Oct 31 (server time), which means that no days can be missed if you want to complete the event. The attendance was not available, however, until after the update on Oct 18. The game went up ~1pm PST, which left only 4 hours in the first "day" to complete the attendance. I have no issues with strict events that require participation every day, but it seems ridiculous to only have a 4 hour window for completion. I was personally unable to complete it due to my work schedule, and I'm sure that other people weren't able to complete the attendance due to work, school, being in a different time zone, etc.
In the past, there have been times where Nexon compensated the first day(s) of an event if it could not be completed. I hope that a free stamp can be given out to cover the people who missed the first day.
