Hearts of iron 4 achievements are fixed

I just got 2 of them that were unattainable. I'm the first to get then as well. Finally got a legacy. :p

The achievement score and the trueachievement score are the same. They should not be. Some of these are really hard. Now there still is achievements that were tied to something. I want to say the dlc. That was never released. So why are those achievements up there as well?

As for the scores being the same, that is normal. It will fix itself eventually, when the site does a recalculation for the game.

Unobtainable achievements automatically have TA score equal to their gamerscore. Once the flag is removed by the flagging team, the next time the site recalcs the scores it will autocorrect.

As for the unreleased DLC, those achievements don't go away just because it didn't release. The achievements are still in the list, and you'd need to talk to the devs about removing them. Until that happens, they're there to stay.
