SUBSIM Radio Room Forums - Start a career before December 7, 1941

Hello,
I decided to make a mod that allows you to start a career Dec. 5, 1941.
I have created all the necessary files and directory, but the japanese air attack on Pearl Harbor is not going as planned.
Fushida's squadrons arrive at 250 meters above the harbor at 08:00 but do not attack or drop bombs and torpedoes on battleships. In fact, the battleships do not replicate either, nor my crew who wanted to defend the homeland.
The planes fly joyfully wings, pilots are "hello" to the American sailors and go to the Nagumo's aircraft carriers.

Here are the files created or modified:
Data/Campaigns/Campaign/Campaign.cfg
Data/Campaigns/Campaign/Patrol Objectives/Avant-Pearl 01/Avant-Pearl 01.mis
Data/Campaigns/Campaign/Patrol Objectives/Avant-Pearl 01/Avant-Pearl 01.tsr
Data/UPCData/UPCCampaignData/CareerStart.upc
Data/UPCData/UPCCampaignData/Flotillas.upc
Data/UPCData/UPCCampaignData/PatrolObjectives.cfg

Does anyone have the bright idea to get me out of this impasse?

In advance, thank you.
