I do not know why, but for some reason I'm not whitelisted on Annihilation. Other players are also having this problem. However, my brother is playing right now with others. I still wasn't able to join, even before the game started.
Ok so basically what happened is @Supere switched what’s called a proxy, however this proxy doesn’t think Annihilation is the same server as the old proxy. To connect to annihilation you would need to connect to the old proxy aka The British Proxy not the Canadian one until Eli fixes it. Essentially the problem is just inconsistency.
