Was asked to participate in a survey, but the survey was already done for me?

As the title says, I got an email from Riot a bit before noon earlier today, but I couldnt take it then because I was at work.

So I come home and remember I have a survey to take, so I click the link, and the survey page it links me too thanks me for my time spent taking the survey, even though I didn't actually get to take it.

I like taking the surveys, Riot. :( Why you do dis to me
