hi, i completed the game, fixed up the reactor and the epilogue had me on vacation with a fancy house with a sauna in finland, i have a cool coffee machine, etc. but i didn't get any achievements? what do i have to do to get one of the "Complete INFRA" achievements?

is there something else i need to do after the credits in the epilogue? or is the game just bugged out? i *just* completed it like 20 minutes ago, and i was connected to steam so that's not the issue… help?
