I am not sure if this is a known issue but tonight was streaming on twitch (https://www.twitch.tv/videos/343402097) and having a lot of crashes. They seemed to be wrapped around Torpedo Events.
I could never get past the first survival scenario where I would charge up all my torpedos, go into emcon and fire torpedos at the enemies. It was guaranteed to crash the game. I tried it several different ways and the same result. Anyways I wanted to point it out and give you the video to show it.
The game is very fun btw.
