AFK check error

So this has happened a few times now, i click the check mark and it says "you are ready" like it should and when the timer runs out that changes to "You have declined". at first i was like, what have i done, but now i make sure i spam the spot where that check mark is with clicks and it still might happen. yesterday my wait time went up to 15 minutes before I just gave up and did stuff other than video games (which was great, maybe dont fix it until summer).
