At the start of games there's an issue with chat. If I choose my spawn and click START ANNIHILATION, often when I press 'Enter', the chat dialogue doesn't appear and I get the 'Click' noise instead, as though I'm clicking START ANNIHILATION every time I press 'Enter'. Basically I can't talk to anybody else while waiting for everybody to pick their spawn spots after I've picked mine. I know it doesn't only happen to me, but it doesn't seem to happen to everybody
