Ive made some mods, but only changed the gfx files. I played ironman regular difficulty from 1936. I was expecting to get We'll build it in a day, The bell tolls for us, Operation Sea Lion and Big Entente.
Hmm, interesting. Two of those I KNOW for sure can be achieved (as I got them, in 1.0.1) so it's not that the achievement itself is broken..
They're also not exactly the most complicated achievements requirement wise, so it's unlikely to be that the requirements aren't actually met while you think they are.
Checksum correct, 1936 start.. I got nothing :/
"We'll build it in a day" is especially perplexing (the others I could conceivably see an issue with civil wars or something like that) since it's the absolute most basic in achievement requirements.
Does reloading a save where you have fulfilled the requirements help at all, or does it stubbornly continue to refuse to award the achievements?
Actually, one thing comes to mind.. Are these games freshly started with the fully released 1.0.1, or were they started in 1.0, or in a beta patch? [it SHOULDN'T affect things, but that's the closest I can come to a logical explanation at this point]
