It should also be mentioned that if you see 5-10 challenges in a row from one person, they are almost certainly using Game Guardian to exploit the "Match Not Started" functionality in the game.

Whenever I get a crash like that naturally (I seem to get more crashes lately), I try to use it to my advantage, especially since I just lost 3 energy for nothing (it eats another 3 energy when you click to start a "Match Not Started" fight). But I've never seen this result in more active players in my list. I wish it did. I think the OP just got lucky.

BTW Berry, I get an "Active Challenge" replaced with another "Active Challenge" upwards of 95% of the time. I consider it a glitch if I don't. Because of this, I always finish my active fights first before issuing new challenges.
