Co-Op Commanders Bug - Chain Of Ascension

Playing on Chain Of Ascension. Myself as Dahaka and the player I teamed up with, SoulOfDevil, playing as Raynor.

About halfway through the match the level’s triggered audio with Ji’nara and the Commanders just cut out with their animated comms pics stuck on screen. As far as I am aware we both experienced this. What I do know is that we both experienced the end of the level not actually triggering. It took a lot of waiting for the camera to be pulled over Ji’nara and casting her opponent in to the Pit Of Sacrifice…and then nothing. We both waited a good while before having to give up and Alt+F4, losing all the exp.

This has never happened to myself before. Is this a known issue for this map or something the latest update stealth-tweaked and broke?
