So, I imagine this is a bug that'll get patched immediately, as it benefits the player, but for the second time, I've gotten multiple emails giving me my arena rank payout.
A few days ago, I got two emails. Today, I got three. Each one had the 600 Arena Points I was supposed to get for being in the 500-200 bracket. I'm not COMPLAINING... but it might be considered exploiting if I don't mention it, and I'd rather not get banned.
