provinces revolting

I know there was a fix done for it but have a few questions on it

1. If an army stack takes a location that instead of attacking they move into it then the damage will be minimual instead of most of the buildings disappear and moral goes to 25%

2. If location is attacked say by infantry then damage would be more but not as much damage as attacking with bombers and artillery/railguns

If you can figure out a percentage that would be great.

1. Moving to take over all buildings are intact but the moral be half of what it was

2. If attacked by infantry buildings be reduced by 1/3

3. If bombers and artillery and railguns are used then buldings to nothing and moral to what you have now.

Thanks
