I know Bungie has all ready said they have noticed the problem where sometimes the invasion portal in gambit not activating but I wanted to make this post to let the people at Bungie know that it happened to myself in case they needed more examples. It happened to my team on Oct. 13 in a match that lasted from around 11:30am to 1200pm EST.. The first two rounds were normal but on the third round the invasion portal never activated at all, even on the first deposit of 25 motes. The opposing teams portal worked correctly the entire round. The portal continued to stay inactive when the opposing team summoned their Primeval.
