This only started happening during season of the Drifter. My game will freeze after the launch countdown reaches 0 or right after matchmaking has finished. It also just froze right before the bridge encounter in Reckoning tier 3. I'm getting pretty tired of the freeze happening, especially since it has happened about 3-4 times per night. Alt+f4 does not exit the game at this point, and ctrl+shft+esc doesn't let me access task manager. The only two ways I have found that exit the game are ctrl+alt+del and then choose task manager to close the game or to hard restart my computer. Please fix this issue, I'm not sure why it keeps happening, but it's keeping me from enjoying the game.
