Why just don't remove all the orders/conditional orders in all task groups ? the AI or NPR can continue and create new orders. at least in most of 4x games...
EDIT : I actually find the designer mode password , Accidentally.... , after several hours of reflection I decided to do it, even if that does not work my last resort will be deleting the NPR , but before i tried anything i save the original database in 3 different locations if i have a problem and i'm gonna try to remove all default and conditionnal orders, they are frakking hundred ! but to play Aurora again , i need to do it , can't wait x)
EDIT 2 : So i tried... but don't want to work, so i just delete the NPR , It is disappointing but necessary
