All of suddenly my games start to crash to desktop. -.-

I'm like, click next turn then the game will freeze up and I get frustated and click somewhere on the screen and it will go white and I click again and it CTDs for good. HALP I have fun game in progress atm.

I'm thinking it's because there's too many units or something more lame.

Only workaround I have found is to zoom all the way out to the world Map mode at max zoom out and then the game probably won't crash when I click next turn I thought the game was just going crazy since last night, but yeah the problem is real. Coz it crashed again just now.  -.-

What info will you need because I would like to continue where I left off asap cuz I just conquered Bash Fissure wildlands and is itchy for a fight with Morian, haven't fought him before.
