[2021] Achievements Disabled?

I've seen this happen occasionally with this game over the years. Usually after some sort of outage, computer crash, Steam problem or something like that . Anything like that happen?

As far as prevention goes, all you can really do is make a backup copy of the ironman save file just before or after each play session, so you have somethign to fall back on should it happen again. But it is a VERY rare event! Which is why the devs have not been able to duplicate the issue so they can fix it.

Sorry this happened to you!
