I have fixed this problem (I think). The code to seperate sprites that
run into each other was commented out for rotating sprites. This worked
before as the equivalent code for not rotating sprites was executed, but
the fix prevented this. I just un-commented the code and added the
needed variables to enable sprite seperation for colliding rotatable
