v22 is released later today. Don't worry about SVN if you don't want to for now - just grab v22 tomorrow and see if you still have the issue. Edit - I just checked and I can confirm that v22 has no crash on end turn from your save game (it plays through to the next turn fine). Whether it will be a viable game position when upgraded to v22 I'm less sure of The assyrians destroy hordes of your units that first turn (dunno if they did under v21 too, or if that is down to the AI improvements since v21 was released). Also the addition of crime in v22 is going to be something of a shock to the system for mature games that have been built up without any regard to crime fighting (though that applies to the AI too, so it'll not be a hardship only the human player bears!). In your game the crime rate in Moscow is 131 aftr the end turn, and increasing at 146 per turn, so it's likely to be crippling pretty fast (anyhting over 500 is going to hurt!). I'm guessing any mature game save from an earlier release will have big problems, since you probably never built any of the anti-crime buildings because of their gold consumption and no huge benefits (before v22 that is). Handling it will require rushing all the crime fighting you can, but the crime rates are so high that they may just swamp people before they are able to do that.
