We seem to be having several issues with things not sticking.
At least 2 of us in my guild did war registration, and now we have a message that we've been opted out for the week.
I'm server 9 and been with this guild for almost 2 years. We've never missed a war. This is pretty frustrating for the whole Guild.
Both of us that registered are different. One is an iPhone, and I'm android through Amazon.
