I was playing 'Meeting at Cementary Ridge' in multiplayer. My Union opponent (why do so much players stick to Blue hmm...? ) captured the point fairly quick. Still, I managed to take over slowly but steady, and after a while i was obviously controling the area AND the point.
But it never turned red, until I lost the game. I guess this will be fixed in the v1.1 patch as "Fix of some multiplayer objectives not being able to be captured easily" is announced?
