I can't even write to CS because it counts as leaving the game, so I open myself up to attack. It's a double whammy as I lose medals from the attack, usually while I'm sending in a report about a bug that caused me to lose an attack.
That happened to me last night. I wrote CS about a base that causes crashes (and subsequently made me lose 39 medals when I'm SO close to 3100...grrr) and during writing I was attacked and lost 21 more. Extremely annoying.
