I just spoke with my opponent. An hour ago, we were going to play on Beta. He sent me a message at that time asking me if I was ready to battle. I responded about 15 minutes later with a yes. He was still online at that point. For around 45 minutes I have been idling on the Beta server, waiting for a challenge / VM, but it never came. Just a couple minutes ago, AuraRayquaza got offline. This exact same situation happened late last week; he asks if I'm ready, I say yes, and then he leaves.
AuraRayquaza, if you're reading this, stop being a john and let's throw down.
