I've been caught again by the feature(!) that progressively shuffles treaty IDs down the list but maintains their original location for cancellation purposes. I want to cancel a treaty existing from game start but there are now so many 'un-cancellable' Casus-Belli treaties in the way that I can't use Jim's trick of temporarily 'withdrawing' intervening agreements to restore it to its original position.
I've gone to the savegame data to try to modify it directly there, but I can't for the life of me find where that info is kept. I've looked under 'treaty' and 'defensive' and 'apes' and 'ape's knees' (for any Bob Newhart fans) but no joy. Any advice on how to manage this situation would be appreciated.
