Right when the weekly reset happened, I was in the middle of an elite territory control with a Hyena heavy after me and the invasion screen popped up and took control of the game. I couldn't do anything for 15+ seconds while hoping that I wouldn't get killed because I couldn't see or do anything.
I've been playing since launch and I've only ever had this happen when fast traveling or coming out of loading screens, which isn't a big deal. But for it to happen right while I'm in the hardest part of a fire fight? Is this a bug or an oversight? Either way, it's not acceptable to wrest control of the game from players while they're in combat.
And before you ask, no, I don't have video or a screenshot because I was in cover one second blind firing at the Hyena heavy and the next this crap happened. When I was finally allowed to hit space and skip the invasion screen, I was too busy running from the heavy because he was still after me.
