This just started with 1.7 Beta. Game runs fine for about 30-50 turns and then the screen goes black. Game is still running, I can hear sound and Task Manager says game is running, but video never comes back. I have to kill game in Task Manager. Never saw this with 1.62.
Insane map size, all Major & minor races activated.
