Two more questions:

I increased the numbers for the castles you mentioned but in the game when I right click a castle, it still says the usual capacity number. I also tried starting a new campaign with no results as well. All I did was replace numeric values in the Gnome Editor. I didn't touch anything else. Am I still missing something?

Also, can I change the seige time as well as the garrison number? I basically want to make castles more valuable since they are currently just death traps for any troops that retreat to it.

If there was a way to keep the buildings from getting destroyed when retreating to the castle that would be another thing I'd like to do.

Thanks again for your help
