I just played a few games of Extraction and one ended in a draw (0-0) despite my team winning both the defending and attacking round by eliminating the other team. It makes sense that the defending team doesn't get any points for eliminating the attacking team (duuh, it's their only winning condition except the timer), it's more like preventing the attacking team from getting points. But the attacking team should definitely get a point for eliminating the defending team, thus ending the round. Or the game shouldn't end before the attacking team extracts the ticks or the timer runs out.
