#Bug

My opponent in a debate recently forfeited a round and I got an email saying I was the one who had forfeited. This caused me to be alarmed for a split second before I realized it was a mistake on the part of the email system. Is this a known bug or just a weird glitch that happened to occur? 

I’m getting a bug where the little orange dot next to the green envelope won’t go away, no matter how many times I open all my messages.

How do I fix it?
