Like many people, I've run into the infinite end turn bug where nothing happens until you reload.  It happens so frequently in my games that I've had to stop playing - literally having to reload every 2-3 turns.  That's no way to play a game!

Anyway, I finally narrowed it down a bit.  This ONLY happens, for me at least, when I use the Cheats.  As in, putting it at the end of the shortcut to activate in-game cheats.  I played a game without cheats to about turn 260 something without a single end turn bug, but as soon as I started a new game with the cheats enabled, I got the end turn bug within the first 3 turns or so.

What does enabling cheats do to the game to cause this?  Sure, the logical answer here is to just play the game without cheats, I know.  But I don't WANT to, I'd rather get this issue fixed!
