I'm a casual player that connects through Steam and I'm getting this message today: Due to unusual activity on your account, we require additional account security and verification, in order to continue play. Please click here to add a valid mobile phone number to your account. I've 2 problems. 1) I've received nothing from Daybreak as far as an e-mail is concerned explaining what happened to create this restriction. What IS the concern? 2) I don't exactly feel comfortable giving the Russian owned company my cell-phone number...it gives me a bad vibe. And, while I'm sure it's completely innocuous, it's also completely unnecessary if not unreasonable to lockdown my account and FORCE that information from me barring anything short of a data-breach. So, is that what occurred? And, if so WHY THE HECK would they not even bother sending me an e-mail to explain that to me. Has this happened to anyone else? I find it incredibly troubling.
