Was in Battle for Gilneas and towards the end, maybe the last minute or so, it showed us as the horde having all 3 points? Meanwhile we were literally staring at our blue alliance flag we had? Glitch or what?
Glitch. Happens in a few battlegrounds and it appears in a few different ways, but i believe what your map shows is correct, and what your scoreboard shows is incorrect (assuming there is a discrepancy between the two).
