If I'm available I'd be happy to help test this. Not sure about my availability though because I'm traveling a lot atm. I've had all of the issues mentioned in this thread, the most annoying for me has been the live replay randomly ending when the game ends.
Also, out of curiosity is there any possibility of being able to go back in time in a replay? I'd love that feature but have no idea how easy or even possible it would be to do that.
Edit: I'd like that feature enough that if it's possible to do I'd consider personally putting in some dev time to accomplish that if I can find some bandwidth in me to do some more dev work outside of my main job
