The sticker book is only active for so many days. There was a clock telling you that yesterday was the last day to complete that sticker book.
Player_junm69j5 Do not hold your breath. There is a countdown that tells you when the event will end.
Here is what I saw last night, as I was trying (unsuccessfully) to finish my 3rd Sticker album in time:
Now, I would argue that is was unfair to end the challenge at a different time of day than when other challenges/events usually end, without warning when it was showing 3 days, 2 days, etc. The last 24 hours did have an hour/minute countdown.
For people that don't play every 24 hour period, even if you knew the event ended yesterday, I can see why it was a surprise that the event did NOT go until the same "end of day" (Midnight or 1 am Central time usually, new daily rewards at 2 am) as every other challenge or event on the pogo site!
