I won a my first game today and received the achievement "The Meek Shall inherit the Earth" for wining a game without declaring any wars.

The problem is about 50 turns before the game ended, I moved troops in to position, broke an alliance, declared a surprise war, and in like 4 or 5 turns had taken every city they owned. 

hence why I legitimately earned " The Six-Turns War" achievement in the same game.

not sure if it is the cause of bug, but I ended the game by winning the space race. It still had like 12 turns left before it ended by turns.
