This should fix crashing problems. I tested it and played a whole game. It never crashed. Make sure you read all of the README file. Look at the latest two screenshots. They prove how the game can be finished. One of the latest screenshots is about 20-80 Rebel troops against...300-400 Imperial troops...most people couldn't get that far. The last picture is a picture of defeat...just to prove that the game can be won...or lost.
Here is the link to it:
