I know I'm a bit late to the party, but since no one else replied and the table extension was not updated yet, I thought I would tell you how to easily fix it in 4 easy steps.
1. Load your table with extender and activate it.
2. Find "Progress to National Idea" and double click on the address pointer to edit it. (It's under Address tab and should look like this - P->23A20D94)
3. You'll see 4 values: 14, 5CC, 7C and 3AC. They're in a column with arrows pointing left and right next to them. Just click arrow on the right of the second value (5CC) and change it to 5D0.
4. Press OK, save the table and you're done.
Hope that'll help.
I am hereby posting a test version, the save is no longer corrupted now.
Achievements are now possible with the console cheat once more.
One issue that remains though:<COLOR color="#FF0000"> The game crashes if you disable the console cheat during play, so don't.</COLOR>
I am posting the <COLOR color="#FF0000">test version</COLOR> here because you have all waited long enough for this already, I'll fix the crashing issue later
Sorry if there are any issues currently, I can't fix them because I don't have the game installed at my current location. I'd have to fix those tonight.
Edit: there is now a fixed version for the national focus issue
