Spring Challenge Gone

So, I've been playing this and today I was on the last challenge. It's the one that has 3 days. So I was on day 3, and mind you, I haven't missed a day and today I failed the challenge. This is the only challenge in this Spring Challenge that I have failed and after I failed it, it told me a list of characters were tired (or something, I can't remember) and then that was it. So did I really just spend all this time doing this challenge to lose on the last day? Really?
