We have just released a small update for Prologue: Go Wayback! with the following fixes:
Fixed an issue where custom audio settings reverted to default on launch until the Settings menu was opened.
Fixed a bug where custom maps reset to a regular map after loading a saved game.
Resolved an issue preventing achievements from being unlocked in Objective: Survive and Free Roam modes.
Improved rolling weather transitions. You can now see weather changes approaching on the horizon over time.
