Summer had passed and it was winter time like 12 days or so. Day 25. All people who i started with were alive and well.
I went to help a neighbor and next day (before he could come back) the war was over. And I didn't get the achievements:
Diary: We Have Wintered
Epilogue: We made it!
Diary: We Made A Stand (not sure if i had to get this one though).
Almost all achievements in the game belong to at least 10% of players. All but these ones. These three belong to less than 0.1% Maybe some conditions are broken?
Anyway I don't consider a person who went to help someone - dead. It still should count in to achievements.
