logged into steam today and saw it downloading an update most definitely not 1.04.
after a logged into the game i noticed that my steam achievements and my ingame achievements are no longer correct and in sync
steam shows Settlement unlocked and ingame it says it isn't when i know i have achieved it.
likewise ingame it says i have unlocked Highwaymen which i'm sure i haven't and steam agrees that i haven't unlocked it
EDIT:
If anyone else encounters this issue closing banished and then restarting should fix this. if you have earned an achievement while under this bug and it hasn't triggered reloading the savegame in question will trigger it to unlock.
