No need to discuss the fix is in the upcoming patch. Dice confirmed the bug a day after that video and 3 days later that they had found a fix. Old bug just waiting on patch day.
I kind of think BF4 is a big prank, like the developers have an office pool going on who can make the most ridiculous bug/glitch. I expect nothing less from the people that gave Senator Barack Obama the Nobel booby prize right before he went on a 5 year killing spree.
