It turns out Fireburn has attempted to schedule with Cara95 on Monday as he stated in his post, and Cara95 had sufficient time to replay to the post on the profile. Therefore, Fireburn takes an activity win.
Act win given to you due to your opponent's inactivity.
Balandrick's opponent has responded to the profile post; however, due to their inactivity, Balandrick takes the win (If Toooth was active on Smogon, I'd ask Balandrick for an evidence of attempts to show up on PS or make other efforts to make the match happen)
Players who are given extensions will have the first 3 days to complete their matches in the next round. Those who do not call activity or request for extensions until the deadline (around 16 hours left) will have their match coinflipped.
