Experimenting with AI

Hi all.

I am experimenting with AI to be more aggressive in the game.
I have my modified IRAI_0_0_29 in which I have spent countless hours for the AI to be more challenging.
It is even more brutal than SH3 AI, almost impossible to outrun.
But the problem is it only works in single missions, if I use it with WoS 1.5 in campaign game will crash.
Now I have thinking modifying some scripts in IRAI_0_0_41 but it is sooooo time-consuming, everytime I change
a script I need to wait for about 4-5 minutes for the game to load everything, not to mention that I need
to play campaign just to find some DD's to test it.
Does anyone have any suggestion how to test AI in campaigns faster?
I was thinking is there in save game files a coordinates of a players Uboat? So maybe I can change them to be much
closer to enemy ports just for testing? Also any suggestions how to load a game faster for testing?
