Can broken ironman save be fixed?

[moyang]

This is an old ironman save(I believe it was 1.4) that I tried to get Poland can into space achievement, but its ironman state was broken around 1780.

I didn't tried again since playing to 1821 is too painful... but can this be fixed? I heard you can.

I'm not sure where you might have heard that. Ironman saves are encrypted and cannot be edited in any way.

But are you trying to play it under 1.7.3 or 1.4.1?

Since I want the achievement, I will have to play in current version.

Its iroman status was broken in 1.4.1 but it could be loaded as a normal save in 1.4.1
Didn't tried loading in current version but I think it will load properly.
