I have got to the part in the stables where I have to rescue the American soldiers and Chinese people. I have no wall mines and in desperation I followed instructions from a walkthrough - something I try to avoid if at all possible - but disabling the IFF on one of the turrets has no effect on the enemy (it doesn't kill them), and after killing Grinko, instead of everyone dispersing the American soldiers are always killed. I installed patch 1.1 at the beginning but I see there is a patch 1.2 available. Having got so far into the game I do not wish to risk losing my Game Saves by installing the patch 1.2 - as happened in another game some time ago. There would appear to be a glitch in the game. Any ideas anyone??
