Accidentally crashed my own game and losing a domination victory

I didn’t save the game, hahahaha! I had an opportunity to nuke three cities simultaneously, one of them being a 1-pop captured Portuguese city that I planned on razing anyway. I figured, great, get rid of it with my own nuke and simultaneously lower the pop of two other Portuguese cities that I’m going to capture and raze. Nope. Game froze and then crashed. Lmfaooo! I was going to win that game anyway. But damn. I wanted to see the result.
