How to disable a mod in existing save? HELP!

[Pagan_PL]

Hello!
I'm asking because I want to disable Alien Ants mod. I removed the mod from in-game list and delete this :<li>AlienAnts</li>  ...and this:<li>
                     <other>TheAlienAnts5731870</other>
                     <goodwill>-100</goodwill>
                     <hostile>True</hostile>
                  </li>
from save file on the top of it(maybe first 50-80 verses) there it is.

PLEASE Help me with this.
Of course save is broken : endless command line errors, but I have a backup of course.

Ok, I got rid of it - I simply changed the "Raid Commonality" from 50 to 0, in the Alien Ants>Defs>FactionDefs>AlienAntsFactionDefs. Now they have 0 % chance to occur.

Thanks anyway! This is my best game of 2015!
